There are several possible issues I will try to help you narrow it down

You said "I powered the wire direct to the antenna cable."

Did you run power to the power supply (The wall plate with the outlet/light/antenna fitting/switch) or a box of many buttons. or did you feed power direct to the cable to the roof?


If the first. Disconnect the roof cable (And any other cable after carefully marking them) and see if it still blows fuse: YES replace switch/power supply. NO, Reconnect cable and DISCONNECT at antenna

Now does it blow fuse: YES: Bad cable (you have 3 pieces to that cable) NO bad antenna

MOST installs, in the roof is a "Bulkhead" connector.. Though I have heard of one of those going bad, odds are they won't. Likewise the cable to the connector is likely not bad.

But the roof top to antenna section flexes a lot and can short out.

This is why antenna coax should never be wound tighter than a six inch circle by the way.. The center wire can "push" through the foam insulation an short to the outside.

Hopefully it's just the easy to replace cable.

I ran a wire from the 12V fuse block to the wire that goes to the power supply I believe, looks like the red wire ends there. I haven't taken the inside cabinet panel off where I can get to the back side of the power supply. All along I thought it was the light underneath the cabinet that was shorted but not so.
