Sending and receiving radio waves between the radio through the radio antenna in the air transmission. In order to ensure stable and reliable signal transmission, radio station based on the actual situation of application projects, the erection of the antenna height and type selection with specific requirements.
1、The main station
Master for the omnidirectional antenna, to cover the distribution of sub-stations in all directions. If it is open unobstructed terrain, antenna height can be set up by the formula: D = 4.12 × (√ 100 + √ 4) determined that the coverage radius of 10 km, the main station antenna to be erected 10 meters from the ground. Below:
2、Sub-station
Sub-station directional antenna, on the main station antenna. Also set up an open non-stop, set up according to the formula to determine the height. Below:
