Vhf relay. .
Vhf relay. We have sold the products for more than 30 years and have found them to be a reasonably priced reliable solution for RF signal switching. It detects when a radio is transmitting and switches an internal relay to connect your antenna to that transceiver. High frequency and RF (radio frequency) relays are high switch speed, high reliability and RF insulated relays designed for use in computers, testing equipment and radio broadcast systems. It can handle those inevitable mistakes we all make because of the unique vacuum relay inside. Ideal for switching between antennas and / or polarities, it is also perfect for VHF systems where Hi power Transmit / Receive (T/R) function and polarity switching are common. Additional features may include an internal diode, magnetic shielding and hermetic seals. Sometimes you can use inexpensive components as a replacement for the more exotic ones. Ameritron’s Remote Coax Switch lets you remotely switch up to five separate antennas using one inexpensive small control line (like standard telephone wire). . I needed an input relay for one of my VHF amplifiers (up to 200w or so), and had a few inexpensive Omron G2 series laying around, so let the testing begin. The modular design of the Remote Controlled Coaxial Relay accommodates different transmitter/antenna switching requirements ranging from 1 transmitter/2 antennas to 1 transmitter/8 antennas as well as 2 transmitters/2 antennas transfer switching. Additional Notes: This device enables the operation of two VHF radios with just a single antenna. Eliminate a tangle of troublesome coax and have a simple and neat installation with just a single feed line. These are very high quality, Japanese manufactured coaxial relays that are typically used as antenna relays for all kinds of RF switching. This connection will be maintained until the second radio transmits. xap bjklvp tpikn sqmww gykd vam yvpotnxk hyhwhot pit lfque
