EMC design of the antenna tower
1) Using pneumatic power Instead of electric powered mode to switch the antenna polarization.
2) Antenna tower base selected non-metallic materials
3) Application of SSR internally optocouplers to eliminate ground loop, externally strong electricity isolated and varistor eliminating surge technology to reduce the circuit EMC to a minimum.
4) Retrofitting shielding casing around the electrical machine and circuits.
