HotspotRF has spent countless hours testing antennas, tuned antennas, low loss cables, lightning arresters, and Helium gateway placements. This HotspotRF-400 low loss cable is built specifically for the Helium Network and has been tested to show less signal loss than other name brand 400-rated cables of the same length. 

Wondering what a 400-rated cable is? The 400 portion of the name stands for cable thickness. A 400-rated cable is at least .400 inches in diameter. Therefore a 240-rated cable is .240 inches in diameter. What is an LMR cable? LMR simply specifies a brand of cable. That’s it. 

The 15-foot HotspotRF-400 Helium Cable is ideal for placing your Helium antenna on top of a one-story building at the highest point possible. HotspotRF-400 low loss cables paired with HotspotRF tuned antennas help you get the most RF coverage and therefore $IoT out of your Helium miner and geographic location.
