Jim:
You have a very interesting question,
here the idea is how much wind load your tower will
handle
options are from my point of view
1 plus can be Ob15-7 all 1 boom
1 Optibeam OB13-6 10 12 15 17 20 40 , no 30m
secondary beam will be 30m 2 ele from optibeam
OB2-30 other yagi is Cal av labs 30m yagi -if
avaliable- and the f12 model with coils
2 can be OB11-5 and ob4030
2a can be your taste of SteppIR and OB4030 , if you
get this you are in time to place the order , maybe
they will deliver on time the steppIR.
you have the options, the time , check your budget and
make your choice
