sirius antenae bad location?

My Sirius doesnt work with the TC on.

Here's an old post that describes how to solve this problem on a Ford Super Duty. One thing to note is that if your vehicle has both navigation *and* SiriusXM, the antenna used should be dual band, which is what Ford uses.

thanks. will check.

My truck only has the radio. No GPS. If you're has GPS as well, you might need a different antenna. I'm sure there's a different external antenna that would cover both.

Thanks, still confused. I thought the shark fin was also a gps antenna for the nav systems as well as a Sirius radio antenna.

Thanks Matt. Sirius works intermittently when TC is on Truck for me. Will purchase this soon.

It's the pillar between the front windshield and the front passenger window, that holds up the roof. On my truck, there's a couple screws to take out, and the whole piece of plastic sides out. My antenna connection was tucked in right behind that. Ford/Chevy may have their connections somewhere else, or all the way back behind the radio head.

My sirius radio doesn't work at all when the camper is on.
I bought this replacement antenna for $15 on Amazon. link.

On my Ram 3500, there is a sirius antenna connector in the passenger side A pillar. I just disconnected the antenna going to the roof, and plugged this replacement in. The wire runs through the door jam, and I stuck it on the hood of the truck with its magnet. The replacement antenna works perfect. No signal issues.

The cab roof on a GM truck slopes forward so the front is lower to begin with, it hasn't ever been mentioned as an issue. New campers sit pretty tall to clear taller cabs like Fords, so the lower cab height allows the GM antenna to clear easily.
