How and where did you bring the coax back into the truck and up (I assume) behind under or thru the dash?
I actually ran the coax under the cab and through the driver's door. Yea I know, not perfect, but have had no problems since I installed it a year ago. Routed coax under trim under door and up along the side of the dash to the top of the stock top of dash mount on the Volvo. In post #11 I posted a couple of pics of my analyzer results............they were from the wrong truck! That was from the 2019 Cascadia I was in before this new Volvo! PIA to set up! These are the readings from the Volvo.......... JD
