If you have a 2 inch class III receiver hitch, look at the pintel hitch
receiver adaptor plate at http://www2.northerntool.com/product/22067.htm I
mount a 36 inch by 4 inch square steel post horizontally (using square u-bolts
from Northern) and then a vertical 5 or 6 foot by 3 inch diameter aluminum post
with regular HD u-bolts that fit the plate (also available from Northern). You
then have a stable base that you can level with jack screws and fold a 25 to 28
foot mast over the top of a truck or van. Mount the rotator at the base of the
tilt over mast and stack multiple antennas. See pictures of my setup at
