Number of Channels Received!!

[VanAmanda]

I purchased a new Winegard HD8200U and a Digital Stream comverter box. I am 57 miles away from the television transmitters in my area. I hear all these people receiving loads of channels all the time. Why do I receive only 7on a good day? They have a good picture most of the time, but some days I only get 3-4 channels. My antenna is about 20 ft high, so we are going to raise it and order a pre-amp. Is there anything we can do to get more?

Good morning VanAmanda,

Could you please provide your zip code so I can have some idea what channels are available.

Thank you.
