Here is how I've got my screwdriver and 2m/70cm antennas mounted to the MH. The screwdriver is mounted to a 2 section extendable antenna pole that I shortened on each end to fit in the basement and attached to the rear ladder. It is grounded to the frame of the MH and the 2m antenna is mounted on a painters extension pole attached to a front mirror. The yellow plastic handle on the end makes a perfect mount to isolate the antenna from ground. Obviously, none of this is connected going down the road.
