I recently replaces my antenna that I had for 20 years. Last summer it was struck by lighting. I've replaced all the coaxial cable from the antenna on done probably 75-85' run. I installed solid signal 8 bow antennas and couldn't pick up reception from stations I can see from my roof. I should have about 20 station line of sight. I installed a Channel Mater CM-77782 preamp and pulled in 13 stations. last week all of the sudden I have no reception. I've checked and there is power from the insert at 22 v DC. Not getting a good reading around the preamp. Could the pre-amp be bad? (I installed it briefly for an hour or so last year to try and get better reception but it didn't work with old antenna) I was thinking of trying a variable gain pre-amp so I don't over power my sigansl.

Any help would be greatly appreciated
