OK fine. The T-10 is going within a foot of the top so that is not really an issue. What model are the Gulfalpha antennas and how long is the crossboom? Also what model is the vert. tribander and what bands does it cover?
the gulfalpha's are 8l vert and horz. each 2mtr. 12' boom (2.4sq) the 70cm. is the same but 8ft boom (1.5sq.). they will be on an "oscar" boom at least 6ft above the T 10 and then a GP-15 4ft. above them. well talking with a few others around here they just use galvanized pipe with reinforcing of a smaller pipe (inside) about i foot above the bottom ant. Still cheaper than chromemoly & since shipping is almost as much as the mast.
