Relocating the Sirius antenna

Has anyone done this? I've got a Gobi rack and there are occasions where I'm sure it's interfering with reception. I'd like to move it to the top of my snorkel. I guess if nobody has done this, I'll do a write-up.

Thanks.

I did not "relocate" my stock antenna, but I did use the Antenna that came with my Sirius radio and put it in the center of the hood just behind the washer sprayer.

I had to change the antenna location because I installed a foil lined insulated headliner I made, which blocked the stock antenna's reception.

I get great reception now.

I added a GOBI rack and it definitely interfered with the Sirius antenna.

I borrowed a portable Sirius receiver with a signal strength meter on it. I used the portable's antenna and placed it in several different locations as I drove in circles and watched the meter. I found that I could put the antenna on the light bar portion of the rack and I would be able to get good reception facing all directions.

Before I got around to moving the antenna, I moved the Jeep itself from Washington State to Southern California. Down here, I get good reception in most directions without moving the antenna.

I still plan to move it though. However, instead of moving it, I thought that I would just add a new antenna and plug it in instead. Any comments on this plan?

I have not done this (let my subscription expire), however I would think that the best location would be in the center of the sound bar which is a high point, and is made out of plastic so it would not interfere with antenna reception.

That was me. See the pics below for exact antenna location.

What's probably happening with the GOBI rack is it's creating a Faraday cage which acts as a shield against electromagnetic energy. The rack is more then likely blocking the satellite signal.

To eliminate the interference you would have to move the antenna OUTSIDE of the Faraday cage created by the rack. Mounting the antenna on the hood or even to the rack itself will more then likely solve any interference issues. I can attest that my GOBI rack partnered with the mounting location of my antenna did not interfere with my satellite reception.

One more thing to think about is the factory antenna itself. When I added Sirius to my OEM head unit I purchased the Mopar antenna from a local dealer. When I got the antenna home and opened the package I discovered that the antenna uses a stud and nut to mount to the roll bar. This means that unless you want to drill a hole in your desired location you won't be able to use the OEM antenna; unless, of course, the stock antenna is designed differently from the Mopar antenna.

Instead of using the Mopar antenna I purchased an after market Terk antenna from Car Toys for $30 (Mopar's unit was $80). This after market antenna uses a magnet to secure itself to the vehicle's sheet metal so I did not have to drill any holes in my JK. If you go this route make sure the antenna you buy has the appropriate connector and not some proprietary part that only works with a specific brand of electronics. Below is an image of the exact antenna I purchased from Car Toys.

Good luck.
