  I cant answer your exact question, but Ive had a few of those RV signal amps where it didnt really make all that much noticeable difference if the amp worked or not. The old axiom "garbage in = garbage out" applies, if the available air signal is so weak the signal to noise ratio is approaching even, when such a signal is amplified, so is the noise. The thing is if the air signal is decent yet theres several feet of cable and resultant cable line losses, the amps help because they amplify the weak signal butttttttttt that signal is relatively clean i.e. signal is much higher then noise so you end up with a better picture butttttttttttttttttt theres such relatively short cables on RV's its less of an issue. As long as the unit has DC power avaialble (fuze okay and pilot works) only a TV shop would have the equipment to measure the gain the amp is producing and if not the repair cost would exceed the cost of a new unit, so I dont see them as being very repairable in my opinion. If it has power but dont work I cant tell you how to fix it, its like an electronic IC Module with no discrete components for test or repair most likely, so unless you see a broken off wire thats easy to fix and youre convinced its not working, looks like a new one is the easiest fix

Antenna is repaired Coax cable that came with antenna (2 yrs old) went bad.To diagnois  Ohm reading at antenna cable connection is between 7.0 & 8.5  if amplifier is good.  I  had 0 ohms at cable end at switch  Also wire can be checked at antenna with switch on wire should have 12V. I had 0 New coax cable went from 6 channels to 36  Frank
