Portable masts attached to cars  I wanted to come up with some
sort of quickly deployed antenna system for rover/field
day/portable use. As a sort of design guideline, I wanted the
total deployment time to be around 5-10 minutes from parking the
car, to having the antenna up in the air. I didn't want to have
to deploy guy lines either (there's not always a place to put
them.  One scheme that occurred to me was an antenna mast that
attached to the car (using the car as ballast and a mounting
point). You've seen this sort of thing, where you put one of the
car wheels on a plate which holds the base of the antenna, and
the antenna is bolted to the vehicle. The ARRL books have had
pictures of this sort of thing attached to RVs, for instance.
One issue is that the car's suspension system will flex under
the loads from the antenna, causing the mast to sway, but I
figured that's not a real big deal, as long as the mast is rigid
enough that it won't buckle. I really wanted to know whether the
car would be tipped ove
