Key word here is VHF. UHF
DTV works pretty well and as expected. It's VHF to me that is a total disaster to receive in many situations where UHF would have worked.
91XG is a UHF antenna and would do me no good picking up VHF.
I have good reception pointing west at Gainesville FL on UHF using only a Radio Shack U-75R up 23 ft. About 18 ft is enough to give me LOS to Gainesville, but I like to suggest go 5 ft above LOS is possible.
So I have about the tiniest UHF pointing a Gainesville UHF at 25 to 37 miles to the stations and good results.
Then I have the biggest thing I could erect at 30 ft can't give me reliable VHF to Gainesville at 37 miles, nor to Jacksonville at 61 miles.
Now that said it's not the problem with those stations signal reaching me, it does. The problem is not enough of it can be received all the time to over come impulse noise in the day time, but most of the time daytime is not too bad.
But once night falls, there is so much tropo in Florida its a lost cause. Even last night ch 9 out of Gainesville that granted only runs 0.470
KW ERP was wiped out by some skip. Probably either Sarasota at 160 miles or Panama City at 230 miles. The way tropo normally runs in Florida it's more likely WINK in Sarasota at 444m smoking 69.1
KW
Moreover is the fact that VHF reception is so fragile. It works when there is no noise at all around in the environment. Even worse is it takes very very little interference on the same channel from out of town to wipe it out. Judging back when Tampa still had analogs running, the amount of tropo that wipes out VHF from out of town would not even let the most die hard viewer that watched analog deep in the snow able to follow a program.
The oligarchy's desire for a little money ($19 billion) and lobbyists adding not how much to the campaign coffers, took away channels 52-69. How I wish I had been more aware of this before the 700 MHz auctions occurred, as now they are gone forever and VHF doesn't work very well.
