Why does there need to be a certain amount of separation between the outside/inside antenna's?
If objects block the outside signal pickup then wouldn't the roof of the RV block the inside antenna from the outside antenna?
a non metal roof/walls etc. are transparent to the frequencies in question. so you need about 15 ft seperation between inside and outside antenna to avoid feedback. Even an airstream with windows isn't going to provide much isolation. And most objects outside don't block much signal. Thats why a cell phone works in your house.
High water content does block the signal, but few objects have enough water content.
Ok thanks. My manual calls for 25' separation but I experimented and have the 2 antennas about 15-18' apart. I'm getting all green lights on the booster and my signal reading goes from -93 to -63 when placing the phone right next to the inside antenna. So it's working fine.
I've found that with the outside antenna up high (15') fifteen feet of horizontal seperation is adequate as well.
I often go from -120db down to -70db. And there are places we go that w/o the booster the phone has no connection but with the booster I can get a signal in the -100db range, adequate for most use. If the booster can establish communication with the cell tower your usually good to go.
