Introduction To The Radio Communication Tower
- Sep 20, 2017 -

A tower structure and a mast structure used for transmitting or receiving radio waves, used as a radiator for a radio transmitting antenna or as a support for transmitting and receiving antennas. Mainly used in communications, broadcasting, television, radar, navigation, remote control and so on. Communication and broadcasting mainly use long wave, medium wave, short wave (communication also can use microwave) to transmit the signal, the television uses ultrashort wave and the microwave to transmit the signal, the navigation mainly transmits the signal by the medium wave.

The height of radio towers with YUCHAMPO, medium wave and short wave depends on the wavelength (frequency), the coefficient of the earth conductivity, the propagation distance and so on. The radio tower height for ultrashort wave and microwave depends on the propagation distance. The propagation distance of ultrashort wave and microwave is equal to the distance between the transmitting antenna and the receiving antenna along the ground surface. For a flat or slightly hilly terrain, the spread distance can be computed (km) in the type of HT as the transmitting antenna height; HR for receiving antenna height (m). When the actual distance is greater than the propagation distance obtained by the upper type, the relay tower must be set up in the middle.

The antenna structure of long wave, medium wave and short wave used in structure arrangement is often composed of several seats and even dozens of radio towers as antenna arrays, and horizontal or vertical antennas and wire nets are hoisted on the radio tower. The mast plane arrangement of the long wave antenna, the strong directional wave antenna and the shortwave antenna is shown in the figure. For Ultrashort wave and microwave, just decorate the antenna on the single tower. However, in order to meet the requirements of transmission distance, the higher tower is often needed.
