Right, the towers for WCNC, WBTV, WJZY, and WMYT are all within about seven miles of my house, and the signal from stations in the western part of NC/SC would pretty much have to go right through them. In the days of analog, I could get Spartanburg, as well as the triad to the north. Occasionally even Columbia and Raleigh to the south and northeast. Spartanburg was better at times than others, but was nearly always watchable. From the time analog finally disappeared in 2009, until THIS went originally to 3.2 and MeTV shortly thereafter to 18.3, we had no subchannels in Charlotte, so I was missing analog. For what seemed like quite a while, the Charlotte market trailed woefully behind other markets in SC and NC on adding sub-channels. But more recently, digital TV has brought us a myriad of great options, so now we are much better off over-all.

Yea forgot about Mt. Holly being near Dallas. That could very well create overload problem. However there are tricks with filters and attenuators that can be utilized, but you have to be very precise and know what you are doing there.

A good antenna would be an Antennacraft HBU33 or HBU55. Or Winegard 7697 or 7698. The Winegard LNA200 preamp is sold at Home Depot, but the noise specs may not be as good as claimed. You may be better off with the RCA preamp or the Channel Master 7778.
Need to look at where he is at. He is a very short distance from the Dallas Antenna Farm. A preamp from that location is going to have problems.

A pre-amp such as the type you suggest does not improve reception. If the signal isn't there, an amp won't put it there. You can only improve reception by acquiring the right antenna to receive the signal. You should attempt to do everything you can to not use an amp as, as pointed out by the previous posters, they cause other problems. Plus it's another point of failure and additional cost.

The correct antenna is very important, but you may need an amp if you have multiple splits or long cable runs in order to get the weaker signals from the antenna to the TV. But the problem is the stronger signals can cause overload and interference. So dealing with a mix of strong and weak signals can be problematic if not managed correctly. That is where fine tuning comes in, and possible use of attenuators and filters. I do not need an amp to receive GSP channels and WBTV, which are strong. But some of the other Charlotte signals and WLOS do require an amp, and overload seems to cause interference with 13 unless strategically managed.
