The Omron G2RL-14-DC12 Relay Kit is suitable for switching RF from DC to at least 500MHz, and has a low loss and better than 15dB return loss to 450MHz. Due to the contact rating of the relay, it should easily handle up to 400 Watts on the VHF bands. The relay is ideal for antenna switching, but the isolation between the contacts should be taken into account when it is used to switch low noise receive pre-amplifiers. Relay isolation can be improved for a particular frequency band, by fitting an SMD inductor across the NO or NC contacts on the bottom of the board. The board has a control input that is used to switch the relay on by applying a >5 to 14vdc to the CTL pin. Tests on this product can be found of the EME249 Kit webpage. 

The Relay coil voltage is +12vdc
