An update on my antenna choice and mounting for my08 6.4 SuperDuty. Because of my heavy work load for now and the trip I'm taking with the Slide in Lance Camper I got a Firestick Fender/Hood mount with a FSII 3ft. stick/ Heavy Spring/FireRing Cable. The cable fished threw the firewall with ease but the mount took a couple of hours/piece of sq.tube for support and some ss bolts..The 08's have changed their fender design so the mount wouldn't work like of 07 and previous.
I get 1.3 on both 1 and 40. with a quick tune..I might get a little better with a good tune trial and error.
I mounted it this way so the over hang of the camper doesn't hit it. It's about a 1 1/2 ft ahead of the over the cab part. Eventually I would suspect I might have to get a NGP antenna on the camper and switch back and forth. I am going to see how this works on my trip or when I get the camper installed and SWR it again.
Eventually I might move the antenna to the roof and take it down when the camper is on..I'm glad I got those Electric lift jacks with Remote for that 4K rig..
