Phasors

When a directional antenna system includes a main and standby transmitter or more than one operation directional pattern,  RF contactors are incorporated into the RF networks to facilitate high speed switching of transmitters or patterns via a rack mountable controller.  The controllers are offered as an electromechanical relay design or as a Programmable Logic Controller(PLC) based design with remote control or web access features.  Depending on the transmitter power level, the antenna matching units can be supplied in weatherproof enclosures, in pre-fabricated buildings, as open panel and shelf units or in mocked up form for installation in a customer-supplied tuning house depending on the specific transmission site requirements.
