After only getting 4 channels, in and out, at our new seasonal site I did some research.
The boosters most manufacturers install are not HD compliant and barely Digital signal compliant.
I replaced my booster with the one sold by Winegard pictured in the link and did the Winegard Wingman add-on. WOW!!!!
Super easy, only a philips screwdriver needed and total cost $100... we now get 12 solid channels and 5 in and out.
