HAMSAT Amateur Satellite VHF UHF Rotary Antennas and HF 5 bands 10 elements beam antenna 20m 17m 15m 12m 10m

HF Antenna.: All the active elements for a specific band do not contain on any case an interlaced element of greater size between the driver cell array and its corresponding reflector or director. The results are a great figure of gain and a very cleanl radiation lobe.

The antenna consists of a logaritmic driven cell that adds an initial significative gain which is reinforced notably by placing a single-band reflector for each of the bands from 20 meters to 15 meters and by adding an additional director for 10 and 12 meters in front of the logaritmic cell array. The antenna is fed through its log cell array, which delivers a greater SWR bandwidth apart of an increase of gain when compared to other single element feeding systems.
