Ok after doing more research then a sane person would. Here is my recommendation. Most of the tv signals are very weak. Install this antenna mount on the high roof part of the house ,

The antenna will be turned aimed at the two groups of tv stations. One group at 81 degree magnetic compass is a weak signal strength group and has these tv stations channels , WBRE-DT 11 NBC , WYOU-DT 13 CBS , WNEP-TV 50 ABC and Antenna Tv , WOLF-DT 45 FOX and The CW and MyNetwork.
