I thought this set was rather unique for the 1970's, so I thought I'd post it. According to the seller, it's receiving a signal (probably a low-powered station) with just one rabbit ear.

Seller lives in southern Wisconsin.

This was called 'The Sportable" by RCA, one of the features was supposed to be a highly sensitive tuner, it's also can run on a battery that's built in to the base, at least the two I have do, it may have been an option.

I would say it's overpriced at $100, I've picked up two of them at Thrift Stores for less than $10 each, one Orange one White, they are not rare by any means.

That one seems to be missing the Smoked Plastic Sun Screen.
