How are you planning on mounting the alum. tubing at ground level?
And what, if any, means are you considering to provide for tipping it
over?
I wonder if it is practical to install say, 4X4 posts in the ground
about 5 inches apart, with another 4X4 as the vertical support for
the aluminum pole. The aluminum pole bolted to the 8 foot long 4X4 at
about the 6 foot level. Would the wood detune the antenna?
