“...I’d like to find an antenna...”
Most of the digital broadcast signal is in the old UHF range. I use an old bowtie antenna meant for UHF. It looks like a piece of wire fence about 2.5 feet tall by 1.5 wide with some bowtie-shaped pieces of wire in front of it. There are instructions for building one easily found on the web.
Bad weather can interfere with the signal, but I get a variety of stations from 35-40 miles away. Some of the “sideband” stuff is a gas — old 50s tv shows, old movies and so on. For example, our PBS (*spit*) station has four “bands” the main station, then (e.g. ) 57.1, 57.2, and 57.3 where one is kids’ stuff, one is cooking, and so on. All over the air.
(Disclaimer: Your mileage may vary.)
I don't get the point of paying for something that's free...bottled water, Sirius and other pay-for radio, towel dry my hair, etc.
Even if I drop cable TV, I'm still stuck with the cable company for computer. They're just plain awful. I pay for inside-cable repair insurance, basically to cover their ineptitude.
