It may not be a problem where you are, but I should think that lightning might come to mind.
Do you really want your GPS antenna up very high? -Chuck Harris Charles P. Steinmetz wrote:
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
