Look behind the plate ... you'll likely find 25 (EDIT: I mean 300 - thanks G!) Ohm antenna wire. Obsolete? Absolutely - espacially since all TV has since gone digital.

I think these were used more for Radio than TV

maybe a single conductor wire ran in the attic and the other was ran to a ground, I could be mistaken but i used to take apart many old radios that would have these, back when the electromechanical speaker would weigh like 25 lbs :), with a big autotransformer driving the speaker.

Anyone know if this configuration was unique to Arrow Hart? They seem to be the only make I've ever seen of these things. I found one of these (the combo with the nema 1-15 outlet) behind a refrigerator in an old house once.

That looks a lot like the one I found several years ago. It was posted here under Nostalgia pages. I believe it was for TV antenna also.

Obsolete? Absolutely - especially since all TV has since gone digital.
The 300 ohm aerial system in my house is alive and well with clean digital signals issuing forth on both VHF and UHF. It's only the modulation that's changed, not the bands in which it is transmitted.
