VB-64DX

6-Meter 4 Elements Beam

INSTRUCTION MANUAL

General Description

Model 64DX is a four element, six meter beam
optimum spaced for maximum forward gain.
The beta match system allows the best possible
match to coaxial cable with the broadest pos-
sible pass band. This antenna now includes
stainless steel hardware for all electrical and
most mechanical connections, and a boom-to-
mast bracket that will fit masts up to 2 1/16
inches in diameter.

WARNING

When installing your system, take
extreme care to avoid accidental contact
with power lines and other overhead
obstructions by any ladder or other
installation equipment. Failure to
exercise this care could result in serious
or fatal injury.
