Columbus was the first to use them when he discovered America.
Based on the “100x better reception” remark, I’m betting it’s a receive preamp. If I recall correctly, I think some other CB preamp manufactures called their product “Linear” in an effort to deceive buyers. I wonder if there’s any writing on the back of the card and I'm curious to know what the 5K pot is about. There was a time that I would buy this item for investigation sake, but not today.
Wasn't these similar to what you'd find in an old J.C. Whitney catalog - called MAKE YOUR WHOLE CAR A CB ANTENNA - No drilling, no mounting - just install this device and it makes your entire car a CB antenna - CB Antenna - antenna?
Cobra had these things too - like a "balun" and you have a hex-key to tune a slug to make it have the lowest SWR - so if you had an AM/FM antenna - this patched in line with the coax connector to the Car radio and the other end had the SO-239 for your CB.
So I imagine this was "Coil" you inserted into the back of the radio - and the wire on the package went to a ground - cold- water pipe and acted a an extra radiator, pickup - Balun even, for the Receive - like a no-ground antenna - extra lead-in for reception.

My first thought was the same.
I put it on my watch list, if it winds up getting relisted cheap enough I might grab it just to see what's up.

Use a 1/2 wave antenna & it does NOT need any ground & they are used a lot in Amateur Radio just because of that.

Awesome. I am not afraid to put a big ass aluminum whip on the back of my Corvette!
