The Hy-Gain 18AVQII is an omni-directional, vertical radiator that operates on the 10, 15, 20, 40, and 80 meter amateur bands. The system will work against earth ground or a resonant radial system when mounted above ground.
The classic AV-18AVQ is back with improved design including three separate air dielectric Hy-Q traps for 10 through 40 Meters. A loading coil and an effective radiator is used for 80 meters -- 1.5 kW PEP.
For best performance, the 18AVQII should be ground-mounted, clear of buildings and other structures. When the antenna is ground-mounted, a radial system is sometimes not needed. In most areas, where soil surface conductivity is poor and a good ground plane is not possible, lay out ground radials to improve the efficiency of your antenna.
