I was going to start a thread, but figured I'd add what I'm going through now. I cut my satellite plan and have been dealing with OTA. I live in a relatively sparse area...between ABC/CBS/FOX/NBC....the towers are about 20 miles away in multiple directions... If I'm able to get Fox, I may not get NBC (though the antennas are very close to each other on the same mountain). CBS is the closest to me, but perpendicular to the ABC and CBS line of sight....(with me in the middle) I'm using a leaf style antenna now along with a signal amplifier. I got a directional one, but it doesn't have the same quality of reception.
My other issue is that my house is like 3400 square feet and mostly one level. (650 square feet are upstairs one one end) My 5 way splitter is on the opposite side of the house of where the antenna makes the most sense to be mounted (because it's the second story). I'm looking at taking my directional antenna and mounting it outside above the splitter and trying to see if it works better as it will have less linear feet to travel on the coax. Even with an amplifier, I get the best signal right off the splitter. As I go back through the house, some TVs don't get the same channels others do. I just didn't have those problems with DirectTV's signal levels on the coax.
If I continue to have those issues, I may resort to using multiple antennas.
