Installed a Cellular booster in rig and an antenna on roof - drilled next to the tv antenna to run the cable thru the roof and ran the cable behind the tv above door. Then put the cable behind the door edging this should get it down to the floor for you to run it to dash.

I have my antenna on the dash also , it's all the way forward at the base of the windshield .
Works great when heading south and can get sporadic when heading north. For the most part it is fine .
Bad dads routing sounds good but I think you would need and extension for the antenna wire to make the trip.
Thanks petew, It is working well in my drive way and I'm parked facing the North. I thought having the antenna back towards the top of the windshield it might be more like on top of the roof. I'll move it around a bit before sticking it down to find the best spot.
This is where my antenna is residing for now, base of the windshield by the wiper arm.
It works well enough that I am going to leave it for now , since I found an extension harness for the antenna wire I may move it later using Baddads route through to the roof.
