3.5-30MHz Shortwave Antenna Broadband 3-Wire Full Band Antenna Dipole No Blind Zone Antenna HF320A Description: HF320A three-wire antenna is a short-wave wide-band (3.5-30MHZ) dipole omni-directional blind zone base station antenna. It can maintain good communication in short, medium and long distances, so it is widely used in commercial field, especially marine stations. It is widely used in fisheries, meteorology, exploration, government, military and other units. It is a reliable and excellent fixed base station antenna and outdoor temporary base station emergency antenna. The HF320A three-wire broadband dipole antenna without dead zone is completely different from common broadband dipole antennas.
It uses a unique three-wire dipole structure, the oscillator structure is double loop type, the radiation is higher than that of single loop dipole antenna (that is, ordinary broadband dipole antenna), the actual use effect is better than that of cage antenna, broadband dipole antenna, antenna for Winton, shortened inverted V antenna, CP-6, staircase antenna, T-type antenna, long-line antenna with antenna tuner, GP, small loop antenna, etc. HF320A antenna has a gain of 3dbi-5dbi through simulation analysis. The performance in the operating band is uniform, the standing wave is small, there is no need for antenna tuner.
No need to lay ground network, and its installation is simple and flexible. There is no blind area for short-range communication, taking into account 360-degree omnidirectional and directional communication. Light weight (1.9 kg), stable installation status, good wind resistance and good tolerance performance, fully meeting the requirements of professional customers.
HF320A antenna can choose two erection methods (inverted V and horizontal erection), respectively adapted to different uses.
