About Narrow-band UHF/VHF Radios

UHF and VHF radio products are used in narrow-band 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.

Number of FAQs related to Narrow-band UHF/VHF Radios: 1

Can more than one antenna be connected to a single radio?

It is possible to connect two antennas to a single radio via a properly specified (operating frequency and power handling capability) two-way, 50 ohm RF power divider. One example of this type of power divider is offered by Pasternack. Note that using a device like this will induce additional losses into the system (3 to 4 dB, typically).
