INSTRUCTION MANUAL
General Description
The Hy-Gain 14AVQ/WB-S is an omnidirec-
tional, self-supporting, vertical radiator that
operates in the 10, 15, 20, and 40 meter
amateur bands. The system will work against
earth ground or a resonant radial system when
mounted above ground. You can make your
own radial system following the manual, or
use the Hy-Gain 14RMQ Radial System Kit
available at your Hy-Gain dealer.
The antenna can be used for either Phone or
CW with either a ground or roof mount. It can
also be tuned to mid-band for use with either
Phone or CW. In either case, the SWR band
widths of the antenna are broad enough that
the antenna will operate at an SWR of 2:1 or
less from 10 to 40 meters. The 14AVQ/WB-S
is supplied with stainless steel hardware and
element clamps for all electrical and most
mechanical connections.

Four Bands Vertical Antenna
10, 15, 20, 40 Meter
Theory of Operation
The use of heavy duty "Hy-Q Traps" provides
automatic band selection. The Hy-Q Traps
are parallel resonant circuits which isolate
the various sections of the antenna and give
quarter wavelength resonance on all bands.
The

enhances
characteristics of the antenna and permits the
antenna to be shortened by top loading it.
