HomeAboutContactProduct DetailsNew Optimised Performance Helium Network Antennas
Specially designed for use with Helium Hotspot miners, all models (i.e. Linxdot, Sensecap, Rak, Bobcat, Nebra and all others).
McGill Microwave Systems introduce the 9dBi high performance antennas for use with the Helium Network, offering superior power transmission compared to other commercially available, non-optimised VSWR antenna designs.
This new antenna design has been specifically tuned to operate with peak performance over only the frequency band of interest to UK/EU Helium Hotspot operators – the UK/EU 868 frequency band.
Most commercially available Helium Hotspot antenna designs available today are designed to be universal – meaning that the one product has been designed to cover both the European EU868 and US915 frequency bands – resulting in designs which may be non-optimised for either frequency range.
We also have different optimised products with tuned peak performance for the different US915 frequency band for USA customers.
Antenna Connector: N Male
You will require an N Female connector on your LMR cable.
Please check our shop for the correct LMR cable assembly you require, or click our links below.
Use the table to help identify the correct connector for your hotspot (this is a guide only, please check your miner).
These optimised antennas feature superior VSWR performance of 1.5:1 maximum – which immediately results in over +7% more transmitted, non-reflected power from your antenna and reduced mismatch loss when compared to many of the commercially available 2:1 VSWR performance antennas.

*Note: LMR-600 SMA connector struggles to mate with SyncroB.it due to overhang of the miner casing.
