Last summer, we set out to build a high-power version of our Relay Station. If you were going to build a better version of goTenna Mesh, which attributes would you choose to improve upon? We decided to tackle range and receiver sensitivity, basically make the goTenna transmit farther and hear distant signals better. We used a 2-watt bullet amplifier that mounts at the antenna (for zero signal loss) and provides 12 dB of low-noise amplification plus receiver filtering. We paired the amplifier with a Laird 6 dBd ISM-band Omni antenna and added separate power supplies for both the amplifier and the goTenna. The amplifier actually uses a DC-injector, which we housed inside the Relay Station's weatherproof fiberglass enclosure. This long-range version is a formidable build and you can expect coverage to exceed 2-3x that of a typical goTenna Mesh unit mounted at a similar elevation. Improving both the forward link and reverse link are impressive achievements in wireless communications, and we are proud with the end results of this product. If you are interested in learning more or would like a quote, please feel free to email us or drop a line on our contact page. We would be happy to run RF propagation plots for your specific location and show you the power of long-range! -TW
