*AND* you want to be certain that the frame of the hitch mounting-to-chassis
*also* has no paint or stuff between it and the chassis of your van, Ed.
Scrape off the paint (of the chassis as well as the hitch mountings) and use
some con-ductive grease to ensure against future corrosion.
If all else fails, you can "bond" the hitch's frame to your van chassis
frame with some copper braid (strip off some braid from old RG-8/U - it's
cheap and works well for this application) in at least two places.... Just
scrape off the paint at the points of attachment and protect the connection
points with conductive grease.
Grease? You can use something like "Kopper-Coat" (made by Thomas & Betts)
or "No-Ox" (made by lots of companies). You gotta' keep that "ground" as
ground!

When you bolt the antenna mount to the trailer hitch make S U R E there
is no paint, no primer, no grease, no debris, no anything between the
mount and the hitch. You want that antenna to have the lowest ac [rf]
resistance to chassis that you can get.
BTW I use hamsticks for 40 through 12 meters and use three bonding
straps to get a VG rf ground.

>> Well, after much thought I decided to go with Iron Horse monoband antennas
on the Dodge Grand Caravan. I am having a trailer hitch installed so will
use a trailer hitch mount. I picked up a new 706 mkII G at Dayton and should
be good to go. Any comments or advice on the mount. Any helpful hints would
be appreciated.
