I did consider that and know it would improve things, but I didn’t want to deal with it at the time, especially with the HOA. AntWEB showed limited choices due to distance and terrain, so I went for broke and got the best UHF antenna and amp I could find.
You really don’t need a ‘special’ antenna.
I’m using my old outdoor antenna that I’ve had up for years and a 10db amplifier that works fine.
Especially since I can ‘rotate’ the antenna in any direction and pull in signals as far as 150 miles away with no problem.
Some channels will still use the VHF frequency from channel 8 through 13.
