SCR-277

It included the BC-467 transmitter with an RF output power of 800 watts, the BC-468 Goniometer, and BC-342 receiver.

[1][2][3] In operation the transmitter sends out signals coded "A" or "N" in each of the four quadrants around the beacon.

The signals overlap on the range, providing the pilot of the aircraft an indication of his position in relation to location of the beacon.

Charts prepared for air navigation show the position and the orientation of the various beacons.
