You will have to adjust this for the specific resonant point you want in the 80 meter band AT YOUR SPECIFIC INSTALLATION. Verticals and baluns . Cebik, W4RNL (SK) Every step along our path through traveling-wave antennas has led us to new heights of gain per unit of wire length (as measured in wavelengths)--and to narrower beamwidths. But when you start looking around, you find that no one can agree on what length to use. It is not essential for both stations to Traditional “cubical quad” antennas have been built using wire on some sort of a framework of poles or other supports, but they can be assembled using wire and rope as well, especially if they do not require rotation, using the same general methods as wire yagis. On this band, the antenna functions as two "long-wire" antenna, each of three half-waves, fed in-phase.
