[TowerTalk] Dual Driven elements.?

[David Robbins K1TTT]

In most designs I have seen they are different lengths.  I think it requires
a very good modeling program because the two driven elements interact
strongly and you need to model the physical phasing line between them
properly also.  The 40m4lldd's that I have use an open wire line with a
transposition between the driven elements, similar to how lpda's are fed.
