Changed the subject line here to be more better. Unlike chocolate, you can have too much amplification. After a point you amplify the "ghosts" and unwanted signals more than the desired signals because the TV's input stages can get saturated and distort.
So far as I know amplification with TV signals, which are F.M., frequency modulated, is only usefull if you want to bring a marginal signal up just a bit. Of course all amplifiers bring the existing noise with them, and introduce some internal noise too. I doubt any amp will bring signals you can't get at all up to a usefull level. I'd also seriously doubt both the 50Db claim and it's usefullness. If a signal is in the noise, amplification will usually not solve that. This is true for TV only, with shortwave it's a slightly different story, although you can still have too much gain. Tom Fowle
