Satellite Radio Interference/Cutting Out

Hola, I have a Sirius XM subscription in my 2013 LR4. I had a trial subscription and I really enjoyed it so I signed up for a full year and just renewed. Problem is that it keeps cutting out all around town. It cuts out at the same intersections on my regular drives around town, same spots on the highways, etc. I've done some research and I understand that it's probably interference from cell towers, traffic cameras, emergency communication signals at intersections, and things like this. Obviously it will cut out in a long tunnel or in the car wash or wherever there are physical obstructions but what I'm concerned about are the interference cut outs. It's become so bad that I'm ready to abandon it but I hate the though of going back to crappy FM stations with short stints of shit music between the main programming (commercials). My theory is that its become worse due to installation of new gizmos at intersections. We don't have much photo radar but we have photo red light running and a lot of DOT traffic cameras at intersections. Of course enough cell towers to fry eggs on the sidewalks. On a side note, I absolutely love the satellite radio while offroading because there are no interruptions. Funny that you have to get out in the middle of nowhere to get a good signal. At any rate, I know my hardware is working fine (perfect signal offroad) but I'm sick of the cutting out around town. Is there any real remedy for this issue?

I've heard that the antenna just gets shit reception. I wouldn't know, since mine has never worked, the wire is cut just as it enters the shark fin.

Do you drive a lot in town with large buildings nearby, trees or such? Either your equipment is not functioning as it should or you are losing line of sight. Either way just do it over your phone.

it was explained to me by an EE I worked with that the bandpass filter in 2013 were adequate for the spectrum allocations, but the roll off wasn't steep enough to attenuate the cellular transmissions in the current allocated neighboring frequencies. Newer hardware is supposed to fix that, but I dont know if it can work with the factory headunit

I've had the opposite experience as you when off road. Wide open Moab and my signal was very sporadic.

When it did work it sounded like a high quality phone call. Price creep made me cancel, long live the ipod.

I don’t think my head unit can do that. It recognizes my phone book but not music. Will have to mess with it.

And rocket science, LoL, I see what you did there.

That’s interesting. I wonder if the antenna pod for a 2013 LR4 supersedes to the same part # for a later year truck. If they call out a different part and it doesn’t supersede I would think you couldn’t switch them.
Another thing that makes me think you could swap the antenna is I keep a test one around and plug it into cars usually when working with navigation issues. I put that in a lot of cars and I’m sure I’ve used it in pre and post 2013 trucks.
