I'd likely continue to use the fiberglass but I might fit a hardwood dowel
inside its length to stiffen it. PVC can work that way too but you MUST have
something to make it rigid. I had a side arm made from wood stuffed grey PVC
pipe that was out in the weather for over 20 years with no
At my remote site I have an inverted L that is supported by a 40ft square
aluminium lattice “frangible" tower. Yes I have it guyed. There is a
14ft fibreglass pole fixed to the top of the tower. There is short piece
of aluminium tubing in the top of the pole and the bend in the L wire is

Probably 15-20 years ago I was thinking of building an LPD HF antenna, I
purchased two 20 foot lengths of 2" x 1/8" wall square fiberglass tubing for the
boom. The antenna never happened and the tubing has been laying on the ground
in the Arizona sun since then. It looks essentially
I've been using 8' 1.5" dia painted fiberglass top and bottom of my 85ft
T as standoffs from a fir tree. An 18" long bracket is lagged to the
tree both places to make it stable and lower the FG stress. OK after 6
years, occasional ice and snow.
PVC gets very flabby at 80F and higher and

I don't have a tower supported Inverted L, but I have a slightly different
way of supporting the center of a 20m 4-square array of inverted L's and
wanted something non conductive so I use 1.5" grey electrical PVC conduit
and it's stood up many years in a harsh environment with wild
I've used a PVC pipe around 1.5 or 2" o.d. and ~ 3 feet long, for the
past 11 years. No problems so far but it is braced with dacron from
the insulator end, back up to the mast a few feet above where the PVC
is clamped to the mast. Mine is unprotected from sun but the sun
exposure is less in

How about PVC conduit, taped to protect it from UV?

I lost my fiberglass pole that I use for a standoff for my inv L off my
50' tower.second or third time in 12 years or so, victim of the
recent ice/snow storm we just had.I've been using fiberglass to
isolate it from the tower.but the wire for the antenna goes thru an
