[TowerTalk] 2-el 15/20 meter duobander

[AA6DX - Mark]

In the wayback, (70S), I contested/dxed using a DB-54 Wilson on a 40' 
boom -- was interlaced 20/15 --  and, the 4 15M elements were inside the 
20M. If memory serves me, this design was in the QSTreet magazine..n'est-ce 
pas? Had it on a W-67 tower, which bit the dust, after I added a 6el Wilson 
for 10M on the tippy-top -- an educating experience!  B U T  -- in the 
meantime, worky-worky!
73 -- Merry Christmas -- Mark  AA6DX

Why not take the measurements from a C3?  I think it is just 2 ele on 20
and 15 with 4 on 10.
