Poor Digital TV Signal

I use this web site it is great. http://www.antennaweb.org/default.aspx You put your zip code in and or street address and it will tell you the stations their direction in degrees and distance from your location. I took a marker and marked on my rotation knob of TV antenna so I would know which was the side to receive the signal look on info for your ant. Then I use compass to get my degree to move my mark to works great. If you have older ant that is not digital ready buy the add on ant for digital less than $30 from CW really works easy to install remove four plastic plugs and line up holes put the four new plugs that came with it you are done. I have sat but some times have to use ant. Also most stations will have from 1 to 4 different channels on one channel i.e. 8.1, 8.2. Good luck. I don't know if they have app for smart phone but may have by now or if know where you are going then look up info before hand and take with you.
