I found some Plans on this groups page for a home made 4 pole
array
for a while. Then see if the plastic
gets hot. If it does, you don't want to use it for RF.

Does really PVC absorb or RF or just act as a dielectric?
The reason I ask is I'm looking at encasing an antenna project for the sake
of weatherproofing and PVC would fit the bill rather easily.

Nuke a test piece and see if it gets hot.

The product I'm looking at specifically is branded as non metallic rigid PVC

I see that YAHOO added spaces to the links in my last post. Remove the spaces
to make the links work.

Hi Joe,
Guess we are all telling our age.
I had WR1AIK in 1975/76. Remember it took a note to my
congressman to get the license assigned - seemed to take
forever!
I was in the AF in Northern Maine at the time.

If you want Laird / Antenex does make a 2 and 4 dipole array for the 2 meter

the 4 dipole antenna. They don't come with a mast pipe like the cushcraft
antennas from long ago. They have a YDA2004 for 200-225 MHZ

On this same topic of the mast-less Antennex/Laird dipole arrays, has anyone
attempted to top mount these from a fiberglass mast to minimize interaction
with the normal steel pole? I have quite a few surplus fiberglass poles left
that would likely work, even for side mounting on 1/2 wave spacing

If you mount the array on a non-conductive pole, won't you then have
to model the effects of interaction with the outside of the coax

Be careful here
Hmm, that would make sense... Back to the drawing board :)

What was the spacing between the tower legs at the mounting location of the
dipoles in your model?

No tower. Only the rooftop-mounted mast 4 dipoles, which is what I was
using at the time.

Comtech I believe has the modeling for antenna side mounting from tower and
it's affect on gain...
