Relay protection consists of two parts

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 which combine transmitter and receiver in one unit. The relay contacts are designed not to reflect any radio frequency power back towar.
