Where radio transmitters and receivers share one antenna, often a coaxial relay is used as a TR (transmit-receive) relay, which switches the antenna from the receiver to the transmitter. This protects the receiver from the high power of the transmitter. Such relays are often used in transceivers which combine transmitter and receiver in one unit. The relay contacts are designed not to refl… WebbEvery time the relay contacts open or close under load, an electrical arc can occur between the contacts of the relay, either a break arc (when opening), or a make / bounce arc (when closing). In many situations, the …
