About Narrowband UHF/VHF Radios

UHF and VHF radio products are used in narrowband RF (radio-frequency) telemetry systems. These systems consist of a radio modem and low-powered transceiver at the remote station(s), and a transceiver connected to a modem or base station at the computer site. Up to 254 stations can be interrogated over a single UHF or VHF frequency.
