I would not series two "boosters' more properly called pre-amplifiers. You'll be amplifying the noise and other signals you don't want more than the T.V. signals you do want, and probably end up with lots of intermod meaning signals resulting from the mixing of other signals in amplifiers that are being over driven and "saturated."
There can most definitely be too much gain in such systems. Get a better antenna first. Especially with everything being new, there is going to be a lot of baseless hype out there and the utility of amplifiers is one area where they'll go after you good since nobody understands saturation. Once you have a signal with no drop outs, more amplification is bad. as it does as detailed above and causes distortion and interference from intermodulation between unwanted signals. tom Fowle WA6IVG
