INSTRUCTION MANUAL
GENERAL DESCRIPTION
This antenna is a 14-element, closed-spaced, two
meter beam. It features high forward gain associated
with a narrow beam width. It has an excellent front-to-
back ratio and is especially suited for DX contacts
where maximum gain and a narrow beam width is
required.

Questions and answers
Wiring diagram?? Why does it look it is a dead short for the connections? The hy-gain instructions aren't good.
The wiring diagram for the Hy-Gain VB-214FM involves connecting the driven element halves to a phasing harness. When stacking two antennas, the driven element halves connected to the phasing lines must be on the same side of the array. The phasing lines are connected to a "T" connector and must be any odd multiple of one-quarter wavelength in 75-ohm coaxial cable.
The appearance of a dead short in the connections is due to the design of the driven element and phasing system. At DC or low frequencies, the connection may appear as a short, but at the operating frequency, the impedance transforms correctly, allowing proper function. This is common in antenna systems using phasing harnesses.
