Last year, we spent a significant amount of time testing with goTenna Pro... in the field - validating coverage, in the office - learning how to navigate the Pro Portal & create frequency sets, and finally building a portable, high-power relay. We tested both VHF and UHF frequency bands and ultimately decided to develop with UHF 450 Mhz due to the smaller antenna sizes and generally wider selection of available RF components. Below is a photo gallery of our field testing and the prototype relay we built. The relay consists of a vented & cooled weatherproof NEMA enclosure with goTenna Pro feeding a 20-watt UHF amplifier, powered by LiPo battery, and includes telescoping tripod mast with 3 dB omni antenna. The portable relay can be deployed in a matter of minutes and is small enough to fit in the back of a small SUV. The relay provides greater than 2x increase in range and during our tests we achieved 9.5+ miles (>90% reliability) with plenty of headroom to go much farther! We tested between our HQ in Oceanside CA and our favorite high point - Double Peak Park in San Marcos CA.
If you have any specific needs involving goTenna Pro, please feel free to reach out. We would be more than happy to consult on your project and have the ability to rapidly prototype custom solutions. We also offer support with Pro Portal administration, creating frequency sets/QR codes for offline deployment, and RF propagation plots for your specific deployment locations. -TW Comments are closed.
