Started having an issue with our (up to now, perfectly working) Winegard antenna on our '01 Limited. Pulled the head off the mast & opened it up, finding it very dirty inside )including wasp nest's & mud dawber nests.
Completely disassembled the head & cleaned it all up. Pulled the wall plate & checked the outgoing
12V signal with a short piece of cable & connected the head unit to my test cable & ran auto-program on the TV & it worked perfectly! Even pulled in 41 channels with the head inside the Airstream!
Put the head unit back on the mast & suddenly the reception is crap again....
Checked the voltage coming through the cable at the mast & found it to start at about 12 volts only to steadily drop to about 7.5 volts. I'm guessing this may be the problem? Only I'm left wondering what could cause this? My guess is an issue with the cable? I figured I'd pull a new one, but it seems the original one may be attached or bundled with other wires inside the walls/ceiling because it doesn't have any free movement in it when i attempt to pull on it?
Anyone have any ideas, what would cause the voltage drop in the existing wire? I find it hard to believe the original cable is broken anywhere inside the walls, but am left with few options.....
Thanks for any info....
