While that location is fine for satellite, it really isn't for OTA TV. Obviously, it was a typical 'quick/cheap' install that the satellite provider did for some type of local reception.
I'm not a fan of AD at all. Actually, what now is available overall, leaves a lot to be desired.
All the local stations are in one direction?
No distant stations?
Free, abundant OTA television separates this country from many others. ATSC1 has only been in force since 2009. The wireless industry has enough spectrum. Enough of 'planned obsolesce'.
