- 设备名称: Three-wire shortwave base station antenna
The three-wire shortwave antenna is a kind of full-band shortwave base station antenna with excellent performance, which can maintain good communication effect in the distance of 0~2500 kilometers. It is widely used all over the world.
The short-wave base station three-wire antenna adopts a three-pole structure, with high radiation efficiency, uniform performance at each frequency point, light weight, stable erection state, strong wind resistance, and no need to match the sky adjustment. When working in the lower frequency band below 10MHz, it provides a high elevation angle, which is beneficial to overcome the communication blind area within 30-100 kilometers. There is strong radiation in the broad and narrow directions, so it can communicate with 3600 in all directions.
Inverted "V" mode erection:
This kind of suspension erection method provides standard 3600 all-round radiation, which is suitable for the communication of the central station to the sub-stations in different directions, and takes into account the horizontal polarization liquid and the vertical polarization liquid, which has a good effect on the fixed station using the horizontal antenna and the vehicle station or the carrying station using the vertical whip antenna. When the antenna length is 30 meters, the central support is 15 meters high. The two brackets are 2 meters high and 18 meters apart.
Erection in parallel mode:
The parallel erection mode has stronger radiation in the broadside direction of the antenna (for example, when erecting in the east-west direction, the north-south direction is the broadside) than in the narrow side direction, which is more suitable for point-to-point communication. The effect is when the bracket height on both sides is 1/4 wavelength.
(For example: F = 10MHz, the height of the support is about 7.5 meters).
