As we all know, staying connected and informed can be crucial. This is why the UKSN launched its Project LoRa initiative, offering a robust communication solution tailored for its members. This guide aims to delve into Meshtastic / Project LoRa, detailing the components, applications, and recommended setups to empower UKSN members in optimising their communication capabilities.
Understanding Project LoRa
Project LoRa, championed by UKSN, is our practical approach to building resilient, low-power communication networks using long-range radio technology. At its core, it makes use of LoRa-based systems (including LoRaWAN concepts and mesh-style implementations like Meshtastic) to allow devices to communicate directly over long distances without relying on mobile signal, WiFi, or traditional internet infrastructure.
Unlike conventional communication methods that depend on towers, data plans, or local infrastructure, Project LoRa is designed to keep working when those systems fail, or simply don’t exist. It’s built around low power, long range, and decentralised communication, making it ideal for real-world resilience.
This makes it particularly useful in situations such as:
Remote camping or hiking where mobile signal is weak or non-existent
Emergency scenarios where infrastructure may be overloaded or unavailable
Rural areas with patchy connectivity
Local community networks where independence from commercial systems is important
Because the system operates at very low power, nodes can run for long periods on small batteries, solar setups, or portable power banks. This is what makes it so effective for off-grid or standby use - it doesn’t demand constant charging or high energy input to stay online.
Project LoRa is also modular by design. Instead of being a single fixed system, it’s made up of flexible components that can be combined depending on what you’re trying to achieve. These typically include:
Nodes – the core devices that send and receive messages across the network
Antennas – which determine how far and how reliably your signal travels
Power systems – from small portable batteries to long-term or solar setups
Cases and mounting solutions – which protect and position your hardware for different environments
Each part can be adapted depending on whether you’re building a portable setup, a vehicle-based node, or a fixed home or community installation. Within the UKSN community, this flexibility is key. Some users build simple handheld devices for emergency comms or outdoor trips, while others create permanent loft-mounted nodes that help extend coverage across wider areas. The system scales naturally from individual use to broader mesh networks, all while staying accessible and relatively simple to build.
At its heart, Project LoRa is about creating communication independence - giving people the ability to stay connected even when traditional systems aren’t available or reliable.
LoRa Node Options for Portable Use
When it comes to staying connected in the great outdoors, during an emergency, or taking part in Charter activities, portability is key. Portable nodes are designed to be lightweight, durable, and efficient, ensuring that users can maintain communication no matter where their adventures take them. Whether you're camping in a remote area, hiking through rugged terrain, or preparing for a survival scenario, these portable options are tailored to meet your needs without weighing you down.
For members keen on customising their setups, starting with a DIY approach can be extremely rewarding and offers considerable savings. We even stock a range of kits and accessories that make constructing your very own LoRa node a breeze!
The Basic LoRa Shopping List
To get started building your own LoRa node, you don’t need a huge amount of kit, but choosing the right components early on will make a big difference to performance and reliability. At a minimum, you’ll need the following:
LoRa Node
This is the heart of your setup. The LoRa node is the device that handles communication over the LoRa network, sending and receiving messages across long distances with very low power usage. Popular options often include compact boards with built-in radios, GPS, or Bluetooth depending on your needs.
When choosing a node, think about how you’ll use it. A simple handheld messaging device is very different from a fixed base station or a solar-powered remote sensor. Battery efficiency, range, and expandability all matter here.
Choosing the Right LoRa Node
When it comes to building a reliable LoRa mesh setup, the node you choose is the foundation of everything. While there are plenty of boards on the market, not all of them are equally easy to set up, maintain, or integrate into a wider network.
At UKSN, we focus on devices that are proven, widely supported, and simple to flash and configure, especially for people getting started with Meshtastic / Project LoRa. That’s why we consistently recommend a small group of Heltec-based nodes. They’ve become popular for a reason: they’re well-supported, beginner-friendly, and generally “just work” with minimal hassle compared to more complex or niche boards.
Below are the three main node types we recommend, depending on your use case and budget.
Heltec V3 (Best All-Round Starter Node)
The Heltec V3 is one of the most widely used entry points into Meshtastic and LoRa networking, and for good reason. It strikes a strong balance between performance, simplicity, and cost.

Antenna
Your antenna is just as important as the node itself, sometimes even more so. A poor antenna will cripple your range, while a well-matched one can dramatically improve performance. You’ll want an antenna tuned for the correct frequency (typically 868 MHz in the UK). Options range from small stubby antennas for portability, to larger external antennas for base stations where range is the priority. Mounting position also matters - higher and clearer is always better. The good news is that all of the UKSN antenna kits below are designed to work seamlessly with the nodes we’ve already covered including the Heltec V3, & Heltec V4. That means you don’t need to worry about compatibility or mismatched connections if you stick with our recommended setups.
Portable Antenna Upgrade Kit (868MHz)
Designed for mobility and lightweight setups, this kit is ideal if you’re running a node on the move or building a compact everyday carry system. It replaces basic stock antennas with a properly tuned 868MHz antenna that is far better suited to real-world communication.
Best for:
Portable and backpack nodes
Hiking, camping, and field use
Vehicle-based temporary setups
Emergency grab-and-go kits
Why it works: Stock antennas are often chosen for size, not performance. This kit prioritises signal quality and practical range while still keeping your setup compact and easy to carry.
Compatibility:
Node

Loft / Static Antenna Upgrade Kit (3dBi Outdoor Ready)
If you want to maximise range from a fixed location, this is the kit to use. It’s designed for permanent or semi-permanent installations where antenna height and positioning can be optimised.
Best for:
Loft or attic installations
Fixed home base stations
Community relay nodes
Outdoor or semi-permanent mounting
Why it works: LoRa performance improves dramatically with height and clear line of sight. This kit is designed to take advantage of that by allowing you to position your antenna away from your node in the optimal location, often in a loft or elevated space.

Battery
LoRa devices are designed for low power use, which gives you a lot of flexibility when it comes to power options. Depending on your setup, you might use rechargeable lithium batteries, standard power banks, or even a permanent mains supply.
If you’re planning a portable or off-grid node, battery choice becomes critical. Capacity, recharge options (like solar), and cold-weather performance are all worth considering if you want your node to stay online when it matters. We offer two main battery options, each suited to different styles of build. Both will work with the UKSN-recommended nodes, but they are designed for very different use cases.
3.7V 1100mAh Li-ion Battery
This is our compact, plug-and-play battery designed specifically for enclosed and ready-to-go builds. It uses a JST 1.25 connector, making it ideal for clean integration inside smaller cases.
Why it’s great:
Designed to fit inside Meshnology-style and compact UKSN cases
Simple JST 1.25 plug-and-play connection
Ideal for portable, pre-built, or enclosed nodes
Lightweight and space-efficient
Best for:
Everyday carry (EDC) nodes
Compact portable builds
Case-based setups where space is limited
Considerations:
Smaller capacity = shorter runtime
Not ideal for long-duration base stations
Prioritises size over endurance
Compatibility:
Node
Case
3.7V 1800mAh LiPo Battery
This higher-capacity lithium polymer battery is designed for users building custom enclosures or longer-runtime systems.
Why it’s great:
Higher capacity for extended runtime
Ideal for DIY and custom node enclosures
Built-in protection circuit for safer operation
Better suited for fixed or semi-permanent installations
Best for:
Custom-built nodes
Base stations or always-on setups
Solar or extended off-grid builds
Users who want maximum runtime flexibility
Considerations:
Larger physical size (won’t fit compact cases)
Requires adapter for Heltec compatibility
Compatibility (With Adapter):
Node
Important compatibility note: This battery uses a different connector setup and will require a JST adapter to work with Heltec-based nodes. We also supply a compatible adapter designed specifically for this purpose, allowing you to safely and easily connect it to the Heltec V3, V4, and Wireless series without modification.
Choosing the Right Battery
In simple terms:
1100mAh JST 1.25 battery → compact, simple, case-friendly, portable builds
1800mAh LiPo battery + adapter → longer runtime, custom builds, base stations
If you’re just getting started, the smaller JST battery keeps everything neat and easy. If you’re building something more permanent, or want your node to run significantly longer between charges - the larger LiPo option combined with the Heltec adapter gives you much more flexibility.
Both options are fully supported across the UKSN LoRa ecosystem, so you can scale your setup over time without changing your core node hardware.
Case
Once your node, antenna, and battery are sorted, a case is what brings everything together into a usable, durable build. It protects your hardware, helps with mounting, and makes your setup much more practical for real-world use.
That said, a case isn’t always essential, especially in LoRa deployments where flexibility matters just as much as protection. We’re actively working on expanding our range of case options to improve fit, airflow, and antenna performance, but in many real-world builds, users take different approaches depending on how they’re deploying their node.
Meshnology Heltec V3 Case
This is our go-to protective case for basic Heltec V3-based builds. It’s designed to give your node a clean, compact, and durable housing while keeping everything accessible.
Why it’s useful:
Purpose-built fit for the Heltec V3 board
Protects against knocks, dust, and general handling damage
Clean cut-outs for USB, antenna, screen, and buttons
Keeps your build portable and easy to deploy
Budget Friendly
Best for:
Portable nodes
Everyday carry builds
Protected indoor or outdoor use
Users who want a clean “finished” look
Things to consider:
Adds physical size compared to bare-board builds
May slightly limit antenna or battery flexibility depending on configuration
Not always ideal for experimental or heavily modified setups
Only works with the Heltec V3
Compatibility: Node ✅ Heltec V3 Battery ✅ 3.7V 1100mAh Li-ion Battery (JST 1.25) - Meshtastic / Project LoRa Nodes Antenna
Do You Always Need a Case?
Not necessarily - and in LoRa networks, many users don’t use a case at all.
For example:
Loft or static installs: If your node is being installed in a loft or fixed position, a case is often skipped entirely. The board is simply mounted securely and left to run.
Custom builds: Many experienced users design and 3D print their own enclosures to suit specific batteries, antennas, or mounting requirements.
Experimental setups: Some test nodes are run completely open-frame for easy access and rapid changes.
The key trade-off is simple: cases add protection, but can reduce flexibility.
What We’re Working On Next
We’re actively developing and refining case options that better support:
Improved antenna positioning for better signal performance
More flexible battery configurations
Easier mounting for static or loft-based nodes
Better airflow and long-term durability for always-on deployments
The goal is to make cases that don’t just protect your node, but actually improve how it performs in the field.
Make It Simple: Build Your Node with UKSN Kits
Choosing the right components can feel a bit overwhelming at first, especially when you’re trying to balance performance, portability, and reliability. To make things easier, we’ve taken the guesswork out of it.
We’ve put together a range of UKSN kits that are designed to work together, so you can confidently combine them to create the perfect LoRa node for your needs. Whether you’re building a portable everyday carry setup, a vehicle-based comms node, or a fixed home/base station, these kits are designed to slot together without compatibility headaches.
Instead of trying to figure out:
Which connectors you need
Whether your antenna will match your device
If your cables and adaptors will actually work together
…you can simply choose the kits that match your goal and build from there.
Each kit focuses on a specific part of your setup, such as:
Core node bundles (device + essentials)
Antenna upgrade kits for improved range
The idea is simple: mix and match depending on how and where you plan to use your node.
This approach not only saves time, but helps avoid common mistakes that can limit performance - like poor antenna matching or incorrect connectors.
If you’re new to LoRa, it’s one of the easiest ways to get up and running quickly. And if you already know what you’re doing, it gives you a solid, reliable base to build from and customise further.
UKSN Basic Heltec V3 Complete Starter Set
If you’re new to LoRa or Meshtastic, the Project LoRa Meshtastic Node Kit (Heltec V3) is the perfect place to begin. This kit is designed as a complete starter setup, giving you everything you need to get your first node up and running without having to worry about compatibility issues or missing parts. It’s built around the reliable Heltec V3 LoRa board, which is widely used in the community thanks to its balance of performance, low power usage, and ease of setup.
What makes this kit especially good for beginners is how straightforward it is. Instead of sourcing individual parts and hoping they all work together, this bundle has been put together so you can focus on actually learning how LoRa works and getting on the network, rather than troubleshooting hardware.
It’s ideal for:
Your first Meshtastic node
Learning how mesh communication works in real-world scenarios
Building a simple home or portable setup
Testing coverage in your local area
Another big advantage is flexibility. While it’s beginner-friendly, it’s not limited. You can start with this kit as a basic node, then expand it over time - upgrading antennas, improving power solutions, or even turning it into a more permanent base station.
In short, it lowers the barrier to entry. You get a working, reliable foundation straight out of the box, which is exactly what you want when you’re just getting started.

Upgrade Your Range: Antenna Kits That Make a Real Difference
Once you’ve got your basic node up and running, the next biggest improvement you can make is your antenna setup. In LoRa and Meshtastic networks, antenna performance and placement can completely change how far and how reliably your node communicates. That’s why we offer two dedicated UKSN antenna upgrade kits, designed to suit different real-world setups.
Portable Antenna Upgrade Kit (Everyday Carry & Field Use)
For mobile setups, backpack nodes, or anything you’re carrying with you, the Portable Antenna Upgrade Kit (868MHz) is the simplest way to boost performance without adding bulk.
It replaces small stock antennas with a properly tuned 868MHz antenna that’s built for real-world use, not just lab conditions.
What it’s designed for:
EDC (everyday carry) nodes
Hiking, camping, and field communication
Vehicle-based temporary setups
Quick-deploy emergency kits
Why it matters: Stock antennas are often compact and convenient, but they sacrifice performance. This upgrade gives you a noticeable improvement in range and signal stability while still keeping your setup lightweight and portable. The included cable also helps ensure compatibility with common boards like Heltec-based nodes, so you can plug in and go without worrying about connectors or adapters.
Compatibility:
Node
Node Kit
Loft & Static Antenna Upgrade Kit
If you want to get serious about coverage, the 3dBi Loft / Outdoor Ready Antenna Kit is where things step up. This kit is designed for fixed installations where height and placement can be fully optimised, typically in a loft, attic, or external mounting position.
What it’s designed for:
Home base stations
Loft-mounted permanent nodes
Community or relay points
Outdoor or semi-permanent installations
Why it matters: In LoRa networks, height is everything. Moving your antenna even a few metres higher like into a loft, can dramatically improve range and line-of-sight coverage. This kit is built around that idea, giving you a more powerful antenna plus the ability to position it away from your node using proper cabling.
The result is a far more stable and far-reaching signal compared to a desk-based or portable setup.

Which Meshtastic Antenna Kit Should You Choose?
It really comes down to how you’re using your node:
Portable kit → best for mobility, flexibility, and field use
Loft/static kit → best for range, stability, and always-on coverage
Many people actually end up using both, one for a mobile node, and one as a fixed “always-on” point in their home or property. That combination helps strengthen the wider mesh and improves connectivity for everyone around you.
The Recommended Project LoRa Setup
To ensure optimal coverage and connectivity, UKSN strongly recommends that members invest in both personal nodes for individual family members and a permenent home setup. Additionally, expanding the network by placing nodes at family and friends’ houses and strategic locations around your town can significantly enhance the system’s effectiveness.
Personal/Portable Nodes
One Per Person: Each family member should have their own portable node.
Stay Connected: When ‘close’ to home, personal nodes communicate with the primary home node and help extend coverage across your local area.
Recommended Portable Meshtastic Node Shopping List:
Primary Home Node
High Placement: Position your main nodes antenna as high as possible - ideally on the top floor of your house or on a rooftop.
Large High-Gain Antenna: Use a high-quality external antenna (where possible) to maximise range and signal strength. Alternatively, loft or even window placements can work.
Always On: Keep this node powered 24/7 to act as the backbone of your local mesh network.
Recommended Home Meshtastic Node Shopping List:
Why This Node Setup Works
A high, powerful primary home node forms the backbone of your mesh network, providing superior range and reliable connectivity. Personal nodes add mobility, allowing each family member to stay connected both at home and on the move.
Combining an always-on main node with portable secondary nodes ensures a balance of range, stability, and convenience, making this the recommended Project LoRa configuration.
Expanding the Network: Nodes at Family, Friends' Homes, and Strategic Locations
To further enhance the reliability and range of your LoRa network, UKSN also recommends placing additional nodes at the homes of trusted family members, friends, and strategic locations throughout your town or community. Doing so broadens your network’s coverage, ensuring better communication reach across a larger area.
Here’s how placing nodes in key locations can benefit your setup:
Extended Communication Range: By installing nodes at family or friends’ homes, particularly in different areas of your town or city, you can significantly extend the geographical coverage of the LoRa network. This allows you to maintain contact over long distances, making it easier to communicate across different locations, even when mobile signals are weak or unavailable.
Reliable Backup Locations: Having nodes at trusted family or friends’ houses creates additional fallback communication hubs. If your home network is down or you’re unable to reach a particular node, the additional nodes can provide critical links for ongoing communication. This is especially useful during emergencies or future large scale UKSN events where backup connections may be needed.
Strategic Locations for Optimised Coverage: Consider placing nodes in concealed or strategic locations across your town. These can be hidden in lofts, sheds, or other discreet areas to boost the network's reach without drawing attention. By carefully positioning these nodes, you can maximise coverage and improve signal reliability, ensuring consistent communication even in urban areas where interference might be higher.
The Ideal Combination for Full Coverage
The most effective way to ensure robust communication is by combining personal nodes for every family member, a home node, and strategically placed nodes around your local area. This approach ensures that whether you're at home, on an outdoor adventure, or managing a critical situation, you have a strong, far-reaching communication network in place.
Mobile Flexibility: Personal nodes provide portability, allowing family members to stay connected whether they’re hiking in remote areas, camping, or simply navigating different parts of town.
Home-Based Stability: The home setup ensures that your home remains a strong communication hub, covering a wide radius and enabling you to maintain contact with family members wherever they are.
Wider Community Connectivity: Expanding your network to include nodes at family or friends’ homes, as well as strategically positioned locations around your town, ensures comprehensive coverage. This also fosters a collaborative communication network within the wider UKSN community, providing assistance and coverage for others in your area.
Future-Proof Your Preparedness
By adopting both portable nodes and setting up a robust network at home with additional nodes in strategic locations, you’re future-proofing your family’s communication capabilities. As the UKSN community grows and embraces new technologies, this setup ensures you’re prepared for any scenario, from casual camping trips to critical emergencies.
Conclusion
Project LoRa represents a pioneering initiative by UKSN to foster resilient communication channels among its members. Whether for recreational outings, emergency preparedness, or community networking, LoRaWAN technology and Meshtastic offers versatile solutions tailored to diverse user needs. By understanding the distinct advantages of each node type and configuring setups accordingly, UKSN members can harness the full potential of Project LoRa to enhance their outdoor experiences and ensure safety and connectivity in any environment.
