Connector type:
LEMO connector EGA 0K 307 CLL
A seven-pin connector is used to provide an analogue voltage representing the received RF
level (0 to 5V into a load of 5k Ohms or more). This provides a convenient AGC metering
aid for alignment of the antenna. The same connector has an RS485 serial interface for
factory set up.
