Careful, though...if you have a sensitive receiver, adding the amp could
actually reduce performance by overloading your receiver and possibly
introduce intermodulation distortion depending on what stations are nearby.
Since he won't be monitoring microwave frequencies, there are several
choices of coax that would work quite well for a 50' run. In reality, there
is some point where the advantage you gain with altitude is cancelled out by
the loss in the coax. For a 50' run, you may be getting close to a wash,
especially for UHF, unless you use better coax. It's difficult to make
comparative measurements because you don't have antennas in both locations
at once, but it sure would be nice to be able to do that.

The best thing you can do is mount a bullet amp at the antenna. Even the
best quality coax has a large loss at microwave frequencies. Use the
type of amp meant for satellite television. Since you aren't transmitting
you'll get by cheap. This will also allow you to use cheaper RG6.
