High Frequency Interference Signal Propagation and Intrusion of Blister Equipment

High-frequency machine interferes with signal propagation and intrusion. Special cable TV trunk cables and user distribution main lines are civilian cables that are laid along the outer walls of the user's house. Only cement poles are set up in empty areas, and there are no power poles hanging around the user's house. In the above, many trunk cables and user distribution main cables pass only a few meters away from the high-frequency machine, and the nearest one is less than 1m (the length of the private house is 10~20m, generally the facility machine on the 2nd floor of the room, and the steel strand is pulled outside the wall on the 2nd floor). Hang the cable, the cable is approximately horizontal and parallel to the high-frequency machine), and then connect several levels of trunk amplifiers or first-level user amplifiers, or direct user distribution.
