At a prior QTH in the 80's I used 3/4" PVC pipe and T's to support a length
of 3/4" CATV hardline as the shunt feed. A single piece of #12 didnt work
well at all at any spacing using bandwidth and pileup busting as the
criteria.

I find that 1/2 inch PVC pipe is handy for many things. It can be cut into
6"
spacers or insulators. I use it for spacers on my Shunt Fed tower's
shunt feed rod. I used 1/2" EMT for the shunt feed rod and the PVC spaced
about
every 24" to stabilize the rod. I use Black Tie-wraps to
secure everything.

I have found that 20 foot lengths of 1/2 inch PVC pipe works very well in
getting radial wires through, around and under the very prickly shrubbery
that
gets in the way here in the New Mexico desert. It is very inexpensive and
can
be extended to as long a run as is needed.
