I do not know if this has all been answered on here already but,

I need to mount 3 beams on a single tower all using the same rotator, =
they are

    a 6el20M with 3el40 on same boom

    a 7 el 15

    a 8 el 10


What is the shortest mast I can get away with without comromising the =
perofmance of the idividual beams. and what comromises work. I envisage =
puting the 15 on top and 20/40 at the bottom. The tower will be at 95'
