Design and research on electric control system for preventing the satellite TV reception system from being damaged by the lightning strike

Since the satellite TV antenna is normally erected at the high place and is easily attacked by the lightning strike,so it is very necessary for studying and researching on the electric control system for preventing the satellite TV reception system from being damaged by the lightning strike.If we have lack understanding to the thunder and lightning and take improper prevention measures for the lightning strike,the lighter it may cause the components damaged,and the heavier it may bring about the persons injured.Each part of the satellite TV reception system including the electric control system,indoor and outdoor units as well as the screening layer of the cable all should be stably grounded.The electric control system and the screening layer of the cable are usually adopted to connect the shell of the indoor unit and the shell of the outdoor unit together and to make the bracket of the antenna to be stably connected with the earth cable of the high building or iron tower.The rationality and reliability of the earth device must be ensured,otherwise,the new earth device should be else buried and set up,and then the lightning rod should also be installed onto the antenna according to the environmental specific conditions of the satellite TV reception antenna.
