magazines, obviously saying they are intended for ham use. What "ham use"
is consistent with the 18 square foot and 10 foot boom specifications?
Funny that Stan should comment on this anomoly. I am considering the erection
of a 48-foot HDBX tower. In its self-supporting configuration, it is indeed
supposed to take 18 square feet of antenna with maximum boom length of 10
feet. I would like to put up a Force 12 C-4XL (9.6 square feet, 30 foot boom)
or, second choice, a C-4SXL (8.4 square feet, 23 foot boom). The square
footage doesn't seem to be an issue, but the boom length of either antenna is
As Stan comments, the value of this reflector is in gathering empirical
evidence. So I seek specific examples of what antennas any of you have put on
an HDBX tower (square footage and boom length), what wind speeds have been
experienced, and how the tower stood up under those conditions.
