A local ham is giving me a 27 foot steel light standard. It is tapered,
going from about 8 inch diameter at the base, to about 3 inches at the
top. It is octagonal in cross section and has a wall thickness of
approximately 3/16 inch. They are originally designed to be free standing.
I want to use this strictly for supporting VHF verticals for packet and
perhaps small 6M and 2M yagis. Since I live on a hill, the height is
perfect for this application.
I have two questions:
1) How does one determine the proper size concrete base? The manufacturer
is unknown.
2) Does anyone have any ideas on how to best mount this thing? I have
thought of setting a suitable sized (8 inch OD) piece of well casing in
concrete, with perhaps 2 feet sticking out, and bolting the light standard
to the well casing after lowering the light standard over it. I will probably
have to fabricate some type of shims to take care of the taper.
Any other ideas?
73,
