You have a decent SWR with the coil on the SIRIO blocked by the cab?My breedlove mount was excellent, got a passthrough with so239 for the whip, and another for the base of the sirio. Think the mount was like 1 3/4" or so I length. Bullring makes a kit to cut the plastic cover on the bed, cheap and works great with a standard router. I sent pic of 192 whip with extension, swr almost flat. Like I say, my garage door is 7 foot, so I can pull in, and drop the sirio down without getting wet, and it is about 1.1:1.

Rig expert aa55 Analyzer says it is perfect..
I agree with Audio Shockwave that the radio is probably the culprit.Dead center of the roof. I’ll send it out was thinking of Q5 communication. I have seen there name all over this site.
Wow! With all those magnets, the roof will lift off the cab when you attempt to remove the antenna. lol...lol...lol!??? LMR400 not good for radio??? RG8U is better? LOL....
For the same length of coax/jumper, the LMR will get more power to the antenna and more signal to the radio. In what way is RG8U better?
Dx.com doesn't have any coax for sale. What "test" are you speaking of?
Here's tuned 1/2 wave LMR400 jumpers feeding a Predator 10K on a Mag mount from a Sweet 16 with 4 watts reflect and 1300+ out on the Bird 43.

Maybe the coil has a damaged wire? Yep! I agree with trying another radio and see what happens to the SWR. What RF Power is the radio set at when checking the SWR? Would that make a difference? Let the experts chime in because I'm just grasping at straws.Although I am fairly new but I am also going to say that the radio is the culprit.
The antenna is basically perfect but when you add the radio SWR goes bonkers.
Going to agree with AudioShockwave and get that radio on a spectrum analyzer.
Do you have another working radio? Just to compare….if possible. But that antenna system is good!!
With the Stryker A10 mag mount. Stryker radio perfect. I guess the mag mount won’t work with the 2970N4.
Rig expert aa55 Analyzer says it is perfect.
Analyzer says 50 ohms SWR is 1.1 on channel 20.
Bingo! The process of elimination is coming to an end.He said " Stryker radio perfect" so I must take it that the only time this cropped up is with the RCI.
If the analyzer says it's good, and the system works great with a different radio what is left to look at?
