Designing a multiband Yagi takes a LOT of work.
Why not just put up the TH6?
I tried interlacing a 3L15 on the boom of my Telrex 3L20.
Bottom Line: The 20M director knocked the gain of the
15M beam down by about 2 dB, acting as an inefficient
reflector out in front. That's why most tribanders use
You can line up Reflectors with no problem.
Another approach would be to use a trapped DE,
separate reflectors and a 10M director, yielding
a 3L10 and 2L15. That is probably the simplest
