If you are going to do a wire Yagi with inverted vee elements, be
certain to carefully model it using EZNEC, 4NEC2, etc. The rules of
thumb for Yagi design yield a very, very poor antenna. I spent hours
trying to create a good antenna and finally cried UNCLE and got help
from someone that had done this before. When dipole elements are not
horizontal but an inverted vee instead, size-able vertically polarized
radiation takes place. Please plan carefully!
Another thought is to build a broadside array instead, putting your
second tower at the proper place.

Thanks for the many informative responses. One question was the size of the
Heliax. I should have said LDF4-50A. I do have about 170 feet of LDF5.
The best idea I have gleaned is to place the second tower so that a line
tied between the two can be used to hang a series of dipoles to make a
stationary multi-element Yagi.
