Ok as the song is titled go up on the roof YOu will need a volt meter or test light and I'd suggest a short piece of plastic straw or tube (Straw very good)( the same length as the probe on the meter leads
With antenna switch OFF (LED OFF) red lead inside straw to center wire
Black lead to "Shell" (nut) on antenna cable (Disconnect from antenna)
Have partner turn on and observe 12-14 volts on meter ... or not
NOT means cable fault most likely
Next step is to disconnect the ANT wire from the face plate (Again turn off)
Replace with a coax jumper and redo the test at the end of the jumper GOOD 12 volt Great nothign blown cable fault confiremd
There is a junction (normally) at/in the roof. It may be stood up under caulking (I have seen one that way) or buried under a clamshell cover (One that way too. Mine)
And in both cases the connection was toast
I replaced the barrel connector (Double female is the technical term or bulkhead connector is another name for it) and both the cable ends and IT WORKED.
Thankfully. I know how to do that and have the tools.
