They use VHF:
"The GoTenna operates on some of the lowest frequencies (151 to 154 MHz) available without a radio license. Those frequencies allow digital signals to travel longer distances. But due to limited bandwidth, GoTenna’s technology doesn’t send voice or photos. "

They would be illegal in
Australia, where we have 80 UHF (around 477MHz)
CB channels with power to 5W and repeaters.
