Mounting a cb antenna on 2014 freightliner cascadia

I tried that mount..No go..SWR was at its lowest of 2.4 and based on my mfj ant tuner my r and x #'s would always closely match..EX swr 2.4 r 35/x42 or swr 2.5 r 23/x 25....I grounded with two ground straps from either side of door hinge and removed one coil off my predators..Nothin changed.Thinking about running two predators as a counter poise to see if that helps..For now im leavin a predator on the back of the cab,frig all range though and its to tall,i hit over passes in ny..

 

How do you make the connection for sat radio?

 

Either via a plug in on back of radio or via fm freq..
