Many thanks to SWLing Post contributor, Dan Robinson, who shares a link to this 31″ Singer Eaton loop antenna found on eBay.
The seller knows nothing about this antenna, but did provide some detailed photos of the connector and product information sticker:
This loop obviously came from US government inventory based on the sticker. It looks to be quite robust and sports one of the balanced antenna connectors found on rigs like the Hammarlund SP-600. I’m guessing this loop might be fixed-frequency as I see no tuning section with a variable capacitor.
Can any SWLing Post readers shed a little light on this loop? Have you ever used one? Please comment!
