Satellite Antennas Site Selection

[Vicky01]

When designing a new satellite antenna station, we must first consider the installation site, which will affect the quality of the transmitted and received satellite signals, the amount of capital investment, and many practical issues such as installation, operation, maintenance. Business personnel should comprehensively consider geographic factors, ground electromagnetic environment, meteorological conditions, safety factors, etc.,
1. Geography environment
1.1 Site of satellite antenna
The site of the satellite earth station should be selected in an open terrain to ensure the satellite antenna launch angle, and also consider the future expansion needs.
Receive only antennas can be installed in urban areas because it does not transmit signals and has no external electrical interference compared with Tx./Rx. antennas. However, it is also necessary to prevent interference from ground microwaves in the same frequency band.
1.2 Weather condition
Severe weather conditions such as strong winds, rainfall, and snowfall will cause the signal of the earth station to mourn, resulting in an increase in the bit error rate of the uplink and downlink signals.
2. Electromagnetic environment
Whether there are sources of interference around. If the interference cannot be avoided, In order to ensure that the remote station can still work normally under interference conditions, the interference level is generally required to be lower than the signal level by 25dB (for TV signals, it should be lower than 30dB).
3. Safety
Satellite communication is essentially a working mode of microwave relay.
First, impact of electromagnetic radiation on the human body
Second, needs to be far away from various inflammable and explosive materials and hazardous chemicals.

Finally, In coastal areas due to severe salt spray and mold erosion, antenna with anti-corrosive reflector surfaces and feed are needed. In areas with typhoons, pay much attention to whether the sturdy supporting structure .
