Keystone RV Forums - View Single Post - Antennae doesn't work and fridge coded after one day of use. 2017 Avalanche 365mb.

Most common causes:
Coax not attached
Center signal wire cut short
Whisker grounding out signal.

Some quick easy diagnosis steps:

Turn booster ON. If you can get to the coax end at the antenna, remove it. Using a Volt/Ohm test voltage from center wire to connector-should see 12VDC. DO NOT ground the center and connector together or you WILL pop a fuse. If you don't have 12V the issue is between the booster and the roof. If there is 12V the issue is probably
between the booster and the TV.

If you can remove the booster plate, with the coax still disconnected from the roof antenna, disconnect the ant in coax from the booster. Test for continuity between signal and connector. Any continuity is bad.
I have special testers that make this a lot quicker.
