some times thinner wall tube may be better.. my towers are designed so the
top tube will bend with high winds (over 80 mph with a given load) thus
saving the tower es antennas.. All "Nally towers" were designed this way,
but many  (most) hams do not relate this es use heavy wall tube so placing
extra load on the tower.. de vk3pa
