Gwx 75 Installation Manual: [top]
High-density d-sub connectors and a specialized RF shield ground block.
The GWX 75 combines the transmitter, receiver, and antenna drive into a single, compact unit. It eliminates the heavy power draw and wear cycles of old magnetron systems.
Personnel must stay 12 feet away from a 10” antenna, 14 feet from a 12” antenna, and 16 feet from a 14” antenna when transmitting.

Connect the radar to an avionics bus via an independent, resettable circuit breaker.
Ensure the mounting structure handles the 11.2 lbs (5.1 kg) weight of the unit.
