Multiple Switching Solutions from Tunwall Radio

Protect coax switches and RF contactors with a controller from Tunwall Radio. Without a switch and transmitter controller, operator error can easily result in a burned out switch and costly off-air time.

Our controllers use a timed sequence to remove RF power, move the switch (or contactor) and verify positions before RF power is restored.

There is protection for a test load as well, as the controller's load interlock circuit will not allow the off-air transmitter to operate unless the load's air or water is running.

A variety of solutions are available, including standard single and multi-switch units, as well as customized layouts and AM directional phasor and transmitter control systems.
