The Hy-Gain AV-18JR HyTower-Jr is the remarkable new HF antenna from Hy-Gain. Its performance is similar to the World's best performing antenna the AV-18HT. This antenna has almost no losses, your ground system determines the efficiency. Stub-decoupling is used to give full-size quarter wave radiators on 40, 20, 15 & 10m.
Requires good ground system for optimum performance.
The antenna is self-supporting in winds up to 65kph (use guy wires for higher winds).
