The biggest issue here is that the ubolts and the holes for the ubolts
to clamp to a mast are not SIZED for a tower vertical member. There
are brackets available which have various sizes which will properly
mate a tower vertical member.
Another issue is that if the antenna is significant, the weight is
unevenly distributed to the tower members, something not true up the
mast.
