DEF

In radar practice, a type of gas-filled electron tube that automatically permits transmit signals to reach the antenna while keeping them from the receiver, but allows received signals to reach the receiver easily.

CONT

The radar receiver follows the transmit-receive tube, which shorts the input during the transmitter pulse. Before the tube fires, it allows a spike of energy to pass. Some tubes require a "keep-alive voltage" in order to be able to fire at lower power levels to protect the receiver.
