Número de FAQs relacionadas con 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).
