really secondary ? Looking for a clearer picture from distant tv
signals. Thanks .
Amplifiers for antennas only work when they are mounted at the
antenna. Quality amps will be weather proofed and have an optional
FM trap that can be switched in if you have a local FM station that
could interfere with channel 6.
Amplifiers other than what is used on an antenna would only makes
sense if you were going to split the signal multiple times.
12 db or 20db makes no difference. If 12db isn't enough then something
is very very wrong in your set up.
Note that if you're having problems, it could be caused by a
too-strong signal rather than a too-weak one. Then, you need to remove
an amp or add an attenuator (Radio Shack may still sell those, as well
as amps).
BTW, a difference of 3db is a 2:1 power ratio.
