This file is the operating manual for 18AVT/WB-S antenna, which introduces the basic characteristics of the antenna, such as frequency range, input impedance and power.
The Hy-Gain 18AVT/WB-S is an omnidirectional, self-supporting vertical radiator designed for the 10, 15, 20, 40, and 80 meter amateur bands. It features stainless steel hardware and heavy-duty Hy-Q traps for automatic band selection, operating with a VSWR of 2:1 or less. The system is compatible with earth ground or a resonant radial system and includes DC ground lightning protection.
