Thank y'all very much !
The MXT275 Midland radio is the first radio that I have ever mounted into a vehical. The small magnet antenna is already up on the roof with the wire simply going through the door just so I could get started. I have one more set of LED lights to go up onto the roof rails and when that install happens I will be running the antenna cord through the roof at the same time. I will be running the DC Power cables up to the lights on the passenger side, while antenna cable will be run up through the roof on the driver side. I really apprecate the comments and insights.
I will be mounting the antenna in the center of the aluminum flat bar, spanning crosswise between the roof rails with a gap of 8 inches between the roof and the base of the antenna. 
Again, thank you for your comments and insights. I will grab and post a pic after the install.

Thanks for suggesting the accessibility suggesting ... I still see small font on this site but I now have really cool hi-vis yellow keyboard on the phone!
