If you have an Winegard antenna, but occasionally you lose signals when you modify the size of the antenna or twist it, the coax may have problems. Start by inspecting the wiring by looking at the distribution panel. It connects to the antenna on the roof.
To allow the antenna for you to reach it, make it rotate 90degrees. You can then use the ladder to climb up to your roof to test it. Unplug the coax wire from your antenna and switch the distribution amp on at 12 volts (measure with a voltmeter) between the coax and the hook, making sure you do not short circuit.
If you have to twist the coax, and your voltmeter’s reading changes as you change the angle, your coax has a problem and will require replacement. An expert repair service for antennas is a great option. They are skilled in dealing with these issues. okus9xryux.
