I'm curious what the best freestanding mast is for a timing antenna
(think Lucent timing antenna or marine "mushroom" GPS antenna --
light and pretty small). The mast would have its highest support at
rooftop or chimney-top level, and could extend from there as far
downward as the ground with additional supports as required. Should
be able to survive at least Category 2 winds and heavy snow and ice.
What reasonably available mast material no more than, say, 3" in
maximum cross-section would allow the most vertical extension above
the highest support, and how much extension would that be? I'm
thinking 10 feet of 2" or so thin-wall steel tube may be OK, but
beyond that I don't know. Tubing is probably not the optimum shape,
but I assume the availability of other engineering shapes (say, "+"
cross-section) is likely to be limited.
Ideas?
Thanks,
Charles
