The Collins IND-650 ADF Indicator is designed to work with the Collins RCR-650 ADF Receiver. Together with an antenna, they form the original Microline ADF system.
The IND-650 is TSO'd and lighted.
The Collins IND-650 ADF Indicator may be used with the following equipment:
- Collins RCR-650 ADF Receiver
- Collins ANT-650A Combined Loop / Sense ADF Antenna (This is a much better antenna than the straight ANT-650.)
