[TowerTalk] 2-el 15/20 meter duobander

[john at kk9a.com]

I played modeling 2el dual banders a long time ago and I recall having
success just putting the higher frequency Yagi in-between the elements of
the lower frequency Yagi. It is easy to model and see what happens. Adding
more elements and more bands really complicates things, kudos to the
designers of the excellent multiband interlaced beams.

Hi all

I have a HB 2-el 20 meter monobander on a 16 foot boom.  I would like to
add 15 meters to this antenna, but can't find any diagrams anywhere for
such an animal.  Googled it but no joy.

Does anyone know of a good setup for 20 and 15 on the same boom without
interaction to each other??  Thanks and 73
