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
essentially at 56ft. The pole is from a wind surf board that was
destroyed in a very big wave. which took four feet of the pole as well.
The wind surf pole is nicely tapered and in one piece. The bottom is about
2 inch diameter tapering to 1 inch at the top. I am not the surfer - I
have a friend who is into this kind of thing.!
It is very stiff and supports the L wire very nicely. The wire I use is a
very small but very strong flex weave type of wire that came from a
decommissioned TCI portable Log Periodic. There is significant "pull" from
the horizontal wire and I have a back stay from the top of the pole to
an outrigger arm at the 30ft level. The back stay keeps the pole nicely
straight and I adjust the tension at the far end to minimize the
deflection.
I don’t know if all Wind Surf poles are like this one but its worth
checking out. I have been using it on top of my 40ft tower for 5-6 years
and it has survived hellish storms with 120kmph winds and ice and snow etc.
