Glass dome intact. Very dusty. One unit does not have dataplate; the other is illegible. Enamel paint is worn, cracked, chipped, across units. One of the connection housings is bent, was likely dropped at some point. Units seems to have all screws still, including retaining bolts keeping glass dome in place. Being sold As Is. Untested.
Antenna component of the ARN-6 Radio Compass, an automatic direction-finder receiver, ranging from 100 KHz to 1750 KHz
The AS313 antenna consists of an iron core loop, rotated by a driving motor. A compensator corrects radio compass deviation error. The loop unit is sealed and filled with nitrogen gas, and requires special equipment to open correctly. The loop uses a low impedance iron core loop of 9 turns, incorporating a 12-turn shunt coil, and electrostatically shielded.
One of the antenna has a faded sticker with an ATOMIC symbol, and "WRAMA," which I believe to be the Warner Robins Air Material Area. The WRAMA was the 21 May 1951 redesignation of the Wellston Air Depot (now called the Warner Robins Air Logistics Center).
