If you’re running a Project LoRa or Meshtastic node and still using the stock antenna, this is one of the most effective upgrades you can make. The UKSN 868MHz Antenna Upgrade Kit is designed to give you better range, stronger signal reliability, and more flexible mounting options - whether you’re setting up a permanent loft install or a more portable node. This isn’t just a single antenna. It’s a complete, adaptable kit built to remove guesswork and make sure you have everything you need to get the best performance out of your setup.

What’s Included
868MHz 3dBi Antenna
A tuned 868MHz antenna designed for LoRa and Meshtastic use across the UK and EU frequency bands.
3dBi gain for improved range and signal consistency
Weather-resistant design suitable for outdoor or loft mounting
Ideal for fixed installations where performance matters
Fitting kit included

This is a significant step up from most stock antennas and is the core of the upgrade.

SMA to N-Type Coax Cable (2M)
A high-quality 2 metre coax cable that gives you flexibility in positioning your antenna.
Perfect for loft installs or placing the antenna away from the node
Helps improve signal by allowing better antenna placement (height and clearance matter)
Reduces interference compared to keeping the antenna directly on the device

N-Type Female to Female Adapter
A simple but essential connector that allows the antenna to properly interface with the coax system.
 
Enables connection between antenna and coax setup
Used in conjunction with the SMA-to-N-Type cable system
Helps maintain a secure and reliable RF connection
Ideal for flexible portable mounting options

This small adapter is what makes the full system work together cleanly, especially when switching between direct-mount and cable-based setups.

N-Type Female to SMA Male Adapter
This allows you to mount the antenna directly onto your node without using the cable.
Ideal for portable or compact setups
Keeps things simple and lightweight
Useful for testing or mobile use

You can switch between direct-mount and extended setups depending on your needs.

SMA Female to IPEX 10cm Extension Cable
Included to make sure you can actually connect everything, even if your node uses an internal IPEX (U.FL) connector.
Designed for nodes like Heltec V3, Heltec V4, and similar
Converts internal IPEX to standard SMA
Included as a safety net - you may not need it, but if you do, you’ll be glad it’s there

This removes one of the most common frustrations when upgrading antennas: incompatible connectors.

Why This Kit Matters
A better antenna isn’t just about distance, it’s about reliability. With a proper antenna and the option to mount it higher (like in a loft), you can:
Improve node visibility across your local mesh
Reduce dropped messages and weak signal issues
Increase consistency in both urban and rural environments
Make your node a more valuable part of the wider network

In many cases, antenna placement will have more impact than the node itself.

Ideal Use Cases
Loft-mounted home nodes
Semi-permanent outdoor installations
Base stations for wider mesh coverage
Portable setups with optional direct mounting
Upgrading Heltec or similar IPEX-based devices

Compatibility
This kit will work with any 868MHz LoRa / Meshtastic node that uses an IPEX (U.FL) connector, including:
Heltec V3
Heltec V4
And many other popular boards

If your device already has an SMA connector, you can simply skip the IPEX cable.

The Ultimate Loft Mount Upgrade
If your goal is to install a node in your loft and maximise coverage, this kit gives you everything you need in one go. No guessing. No missing adapters. No waiting for extra parts - just a straightforward upgrade that works.

UKSN Tip
Height and placement matter more than most people realise. Even moving your antenna from a desk to a loft can dramatically improve performance - especially when paired with a tuned 868MHz antenna like this.
