I’ve got 30 something channels with my OTA HD antenna mounted in the attic.
My wife likes several shows only accessible with streaming (or cable) so I’m constantly looking for the most economical streaming service with recording capability.
We like youtubetv but they are about to tick me off with raising the monthly cost to the point I’m gonna end service.
I’d say if you can try the antenna outside the house just to compare. Attics can block a lot of signal. Then again IF the next group of channels are marginal in value then it’s not worth it. Don’t need a QVC and Spanish language station..
