The HFV-8040 is a rotary dipole for 80 and 40 meters, compact built as usual with qualitiativi standards of Diamond. This antenna is designed as a trap dipole shortened with condensers at the ends. Due to the high accuracy of capacitors, the minimum position ROS can be obtained very effectively in the portion of required bandwidth. Like all antennas shortened, the bandwidth is limited, and it is necessary to use a tuner or need to realign the antenna. The bandwidth without tuner is about 25 kHz on 80 meters and 40 kHz on 40.
When folded, the antenna measures only 170 cm; This makes it ideal as an antenna for the holidays or for use by field. Once installed, the dipole elements are a bit longer than 5 metres; the turning radius is only 3.6 meters V-configuration. The antenna weight is 7 Kg, the balun BU-50 is included (with connector PL). The clamp fits poles from 38 to 60 mm. in diameter.
