From what it sounds like your dad really enjoys his setup. More power to him. Does he ever have problems in storms? I figured either he'd lose reception or one would get blown over out of sheer probability with quantity.
I'm not sure, he is very content with it, He does not regret leaving Dish/DirectTV. I know he's said there are a "few" channels he is working on getting, but he can do without them.
The garage supports 1 antenna tower, the one by the chimney has been there for decades. The CB tower was the 2nd addition. The Monster Antenna I hadn't even heard about, until I seen this picture 2 years after we visited lol... Recently he has added a Cell Antenna boost setup. Before I only got 1 bar off and on (so usually no service), this past visit I was getting 2 bars, and the internet was working somewhat fast. It's really crazy how many waves are being drawn in there. I wonder if a house could implode if too many waves are pulled in?

Not a good thing I'm sure...
When I seen the pic, I focused on the house. Then I thought, oh yea, I wonder what antenna he has setup for that mess in the basement! Then it all came together. There are no antenna joiners in his setup, after talking to him for a bit, most of us could only dream to do that, I know my budget could not afford what he has achieved lol... He's spent $1000 on each antenna setup at least. Filters, signal cancelers among other things. All the duplicate overlapping channels are separated and redirected... Huge mess to me, but in the end, well worth it! I feel sorry if we ever lose the house (the family) as the new owners will be happy to see the freeTV opportunity, then realize an extreme amount of equipment and setup is required to accomplish what "would be if lost" was there...
So, yea. Alien (Check), Porcupine's (Check). I am still not sure what range he is achieving with the antenna's
Cincinnati, OH. - channels are about 60miles S.E (depending where the actual farm is)
Indianapolis, IN. - channels are about 60-65miles West (also depending)
I think one is pointing to Dayton, OH. (complete guess there but that too would only be 60 miles East.
I swore he said he was getting Kokomo channels though... But from the pic, *unless my direction is twisted from the roads* I think he's what I have listed is about right. minus Kokomo.
I'll have to clear the headache I got to try to understand what he told me, and ask what farms he is currently picking up next time I talk to him. I thought the signals were further away, so unless he's going further than what I am thinking of, I'm screaming overkill lol... Then again, bigger the better!!!
