Rich,
You will like the Sensar Pro.  I have used one for over 2 years and it simply takes all the guesswork out of pointing your OTA antenna.  You will even know if you should be getting channels where you are parked.  If the signal strength numbers are less than 50 your chances of reception are poor.  If they are higher than that you can pretty much be assured that you should at least be getting some channels.  If your signals are in the 70+ range you will likely get all the channels.  It takes about 30 seconds to turn it on, raise the antenna rotate until you cannot get a higher number and you are done.
This also is only for the OTA signal and of no use for satellite TV.
