Common cell phone signal jammers misunderstandings

　　Common gps jammers misunderstandings:

　　① The bigger the jammers power, the better

　　1. The host frequency output is inaccurate, the frequency drifts, the bandwidth is too wide, the power is wasted, and the interference base station;

　　2. The shielding efficiency of the simple frequency sweeping power suppression method is not high, and the radiation is large;

　　3. Power false standard, exaggerated propaganda, the nominal power loses its reference value;

　　4. Power is the foundation, and technology is the shutdown. It is better to find good methods and techniques than to fight for power recklessly;

　　② Use directional antenna to avoid interference

　　1. There is a certain transmitted signal strength outside the directional angle of the directional antenna, but it is much lower than the main lobe, not completely directional;

　　2. The reflection of buildings will still cause external interference;

　　3. The frequency drift of the host seriously affects the base station and causes external interference;

　　4. TD full-time shielding interference must exist.

　　③ jammers high-power equipment radiation is large, low-power radiation is small

　　1. High power adopts outdoor antenna function, which has long operating distance, large shielding coverage, uniform shielding signal but very little radiation;

　　2. If the low-power equipment does not use multiple antennas for long-distance shielding, but is centrally arranged or 5 antennas work together, the radiated power will be greater than 10 microwatts/square centimeter, and the short-range radiation must be seriously exceeded
