Carl, K3BZ, sent me three articles on the subject tubular, tilt over tower
made with three 20 foot sections of pipe (starting with 4 inch OD) for a
total height of 60 feet. The original article was published in QST about 40
years ago.
Has anyone constructed this type of tower using aluminum? I am concerned
that using aluminum might result in too much flex but it would certainly be
easier to construct and erect on site. I do not intend to install a yagi,
only a pulley to haul wire antennas up and down so the windloading should be
minimal.
