HD Rececption GS-2200

[Damark0]

I installed the GS-220, outside at the highest point on my roof. I can only get 6 channels. When I use an inside attenna, I get 30 channels. I need to know what attenna I need to install on my roof to get the 30 or more stations?

Good morning Damark0 -

Please provide your zip code or exact address for us to determine what is happening in your area. Also, please check for obstructions such as large trees between your antenna location and the tower you are trying to receive from.
