HF320A Short-wave Full-band 3-wire Broadband Antenna, HF Short-wave Full-band Single-sideband A Q

The overall length of the antenna: 20 meters. It has reliable performance and a communication distance of more than 3000 kilometers. This is a full-band short-wave antenna with a working frequency of 3.5MHZ–30MHZ. It is suitable for you to work in the short-wave working frequency band (different frequency and frequency hopping).It is a government, military, and three defense , Fishery and other units commonly used short-wave base station antenna! HF320A three-wire antenna is a short-wave wide-band (3.5–30MHZ) dipole omnidirectional non-blind zone base station antenna.It can maintain good communication in short distance, middle distance and long distance, so it is widely used in commercial fields, especially maritime. The base station antenna selected by Taiwan, fishery, meteorology, exploration, government, military and other units is a reliable and excellent fixed base station antenna and outdoor temporary base station emergency antenna. The HF320A three-wire wideband dipole no-blind zone antenna is completely different from the common wideband dipole antenna. It uses a unique three-wire dipole structure. The vibrator structure is double-loop. The radiation is higher than that of a single-loop dipole antenna (that is, a common wideband dipole antenna). The actual use effect is better than a cage antenna, a wideband dipole antenna, a Winton antenna, The shortened inverted V antenna, CP-6, stair antenna, T antenna, long line antenna, GP antenna, small loop antenna, etc. are all strong. The HF320A antenna has a gain of 3dbi — 5dbi through simulation analysis. The performance in the operating frequency band is uniform, the standing wave is small, no sky tuning, and no ground network is required. The installation is simple and flexible. Communication, light weight (1.9 kg), stable installation status, good wind resistance, good resistance performance, fully meet the requirements of professional customers. The HF320A three-wire antenna can be installed in two ways (inverted V and horizontal cross-pull) to adapt to different uses.1. Inverted ‘V’ erection . Inverted V erection is mainly used for omnidirectional 360-degree communication without blind spots and long-distance directional communication, and the communication distance can reach more than 2000-3000 kilometers. When the radius is 0-1000 kilometers and the operating frequency is below 12MHZ, there is no dead zone in the communication area. Therefore, it is often used as a central base station in a communication network, and can also be used for a local station to form a reliable communication emergency protection network. When the working frequency is above 12MHZ, the antenna also supports long-distance directional communication. The communication distance can reach more than 2,000 — 3000 kilometers. The front of the antenna element is its radiation direction.. Erection method: The recommended height is 6 meters — 7.5 meters, the included angle of the antenna top is 10 — 120
