Building a marine type HF whip

IF ... you go with any kind of socketing arrangement for joining the
PVC sections, then Mr. Gravity will be your friend -- hose clamps
only.
Related: I didn't go to the home improvement store today to check
availability, but I gave some thought last night to PVC parts that
might make a base. There are some elbow and three-way fittings that
might be adaptable to forming a base. Do you need a way to keep the
thing sorta vertical and/or keep the bottom from kicking out and
toppling the whole thing? It's got to be relatively free-standing
(away from the body of your RV), right?
It is my intent to have some sort of either removable, or possibly
semi-permanent mount fastened to the rear bumper of my motorhome to hold
this verticle antenna. It will be located close to the ladder on the
back of the motorhome and the vertical antenna will be supported in one
place at the top of the ladder with a nylon marine type support bracket
made for that purpose.
Until I figure the actual hardware that will be on the bottom of the
bottom section of this antenna, I will hold off on the actual design of
the base support portion of this project.

Hi Ed
I use alot of PVC pipe to get my VHF antennas up in the air. It is my
opinion that a 23 foot tall structure made from hardware store quality PVC
will never make you happy, especially of it is made of 3 disassembalble
sections. PVC bends over alot in the wind, especially on warm days.
