I'm about to move to zip code 36092 and I'm going to buy a CM 4228. I already have a CM 7777 pre-amp that I use with my HDTVi in 36117. It gets good signal strenght on all of the digital stations. When I move, should the 4228 pick up all of the stations without a rotor? Will the 4228 be o.k. for attic use? Thanks for the help. Any suggestions before I purchase any equipment?
