No amp can improve a bad antenna's reception. You don't need an amp at all with signals that strong going into two receivers, just a decent antenna. See my reply to your antenna question here for more information.

It seems to me like a station would be in the same spot all the time. I can turn the antenna and may find a channel or may not. some ive only seen a couple of times. why is that? i have a vhf/uhf antenna 30 ft with rotor and inhouse amp. will a preamp help me with this problem?
Im seeing that weather has a bearing on reception with this digital crap. In a storm situation the old analog way was great. you could get tv in a storm,atleast viewable tv. i think it was a mistake on the government for this and it will bite us in the ass.but then again i think to much,so ive been told.
thanks:suzzie

GO to www.tvfool and look up your reception information. That will help figure out what conditions you are looking at as far as signal strength is concerned. Do you have both UHF and VHF channels in your area? The TVFOOL data will help determine what can be done for your issues.

Leading industry experts are stating that in 95% of the cases, antenna amplifiers ARE NOT NEEDED !! If the signal is above the receivers noise threshold, amplifiers normally DO NOT help that much. I only recommend amplifiers for viewers in the far fringe areas at 50 plus miles from full power transmitters.

Hi Fox,

Surely the "leading industry experts" make an exception for long cable runs and multiple splits, correct? Fringe situations should also be given some consideration as well as local environmental conditions (trees, etc). 95% not needed seems way too high in my estimation.

One of my go-to guys said the following "use a pre-amp if you can't receive all your stations at a single tv or use a distribution amp if you can't receive (or have low signal strength) on all your channels on tvs further downstream." IMO, that is great advice.

Fox TV,

Can you provide a link for your quote "Leading industry experts are stating that in 95% of the cases, antenna amplifiers ARE NOT NEEDED !! If the signal is above the receivers noise threshold, amplifiers normally DO NOT help that much."

Is the 95% from a field study or a guesstimate by some expert?
