Ultimatley I ended up getting a cheap refirb HDHomeRun DUAL off ebay and used a smartphone app that talks to the HD Homerun to display in realtime channel signal strength. (https://itunes.apple.com/us/app/signal-gh/id289580769?mt=8) (I know there is a similar like app for android but I dont use android so I dont have the link)… These two things were the best way I could figure out which way to point my antenna then check the channel strength in realtime to see if I got it right… I would have to say getting the right antenna and getting it oriented correctly (and testing between attic mount / outdoor mount) was the hardest and most time consuming aspect to all of this … Granted I live 40+ miles away from our “local” TV transmitter cluster… (espcially if you are up on a roof trying to do this … its not easy to try to do a “Channel scan” and see if you got it right… that way can take hours)
