looking for ideas for mounting 2 meter ground plane
 
Hi, I'm going to make a 2 meter ground plane like the one described in
the 21st edition of the ARRL Antenna book, page 18-24. My thoughts
were to put this up on about 20 feet of PVC pipes against the side of
the house. I was wondering how would I attach the SO-239 to the PVC
after I have soldered the radials to the holes of the SO-239. I'm sure
I can come up with something but I wanted to hear how other people
have done this before. Also, maybe PVC pipe isn't best choice for this
type of antenna. I just want to get it up high enough to make the
repeaters in my area. maybe I can just hang it from a tree like a
bird feeder? ;-)

Thanks,

Jim

Hi Jim,

This has worked for me, with a slight detune. The PVC and height
sound OK, but the PVC may just lay right over (fill it with some
insulation foam to make it more rigid).

Jim,
One way would be to just set the base of the antenna on top of the
pipe and feed the feed line down the pipe. Notch an appropriately
sized cap for that pipe for the radials and vertical element. Set cap
on/over the antenna. Fix the cap to the pipe how ever you want to,
glue?
I agree about the unstableness of the PVC pipe., it do bend and
sway if it's very long. So, use a shorter section on top of something
else? Clamp to a vent pipe on top of the house?
Have fun...

This link just turned up in one of my searches. Oddly enough my google
search criteria was "2 meter ground plane coil".

PVC pipe will fold over on you. Unless you use a larger size - like 1-1/2"
or 2-inch.
But hanging it from a tree like a bird feeder will work.
