RTA 1300.A RTR 1200.A RTC 1100.A
Standard Configuration:
The system operates in „remote mode“. The direction finding antenna is installed remotely from the controller,
at a location favourable for direction finding. Receiver, demodulator and antenna control module are integrat-
ed in the receiver unit located at the antenna position. They are connected to the controller by means of a 6-
wire line.
