so i bought a cheap analog swr meter and my midland mxta26 in 3 different locations on the jeep. I dont have specific SWR numbers but I was able to see relative using same cable and same antenna different locations. 1) Highest SWR tailgate mounted to hinge next to my CB antenna. SWR improved slightly when I removed the CB antenna. 2) Side of driver side cowl next to a pillar. 3) best swr on roll bar. Of course with the 36" antenna the top was completely open.
