 Ultra-Low Loss Cable for Helium Miner Antenna


This is the Ultra Low Loss Cable to connect your Helium Hotspot Miner to your outdoor Antenna for the best performance.

It’s equipped with an N-Type female to RP-SMA Male connectors, and RP-SMA Female to SMA Male adaptor is provided to fit any Helium hotspot miner like RAK, Nebra, Bobcat, synchrobit, so you haven’t to worry about the compatibility.

This cable will help you obtain the maximum gain dBi of your outdoor antenna, and extend your coverage area as you expect.

Don’t use any cable with your Antenna?

When we use the radio transmission devices like the Hotspot Miners there’s always some dBi lost in cables and adaptors, so If you would like to calculate the real dBi you will get from your antenna, you need to include the lost dBi in each element between the antenna and the final Miner.

The cable loss factor is called cable attenuation, and there’s a big difference between cables regarding this point.

Below you will find a comparison of different cables:
