What is the reason that the signal jammer does not work or the effect is poor?

There are many jammers on the market today, but many customers do not know how to use them, so the jammers often do not work or have poor results. Do you know what is causing this phenomenon? Together with signal interference shielding Let’s find out about the device manufacturer Chengdu Saiyue Communication:

1. You must order a suitable shielding device according to your needs, which is more important

①If you want to block mobile phones, then you have to choose 2G 3G 4G full frequency signal jammer. At this point, you must consider whether you want to add additional functions such as GPS (satellite positioning) or WIFI (wireless Internet access)!

②Choose the right power supply: portable jammers have low power, easy to heat, desktop jammers have high power and good heat dissipation! The shielding range of desktop jammers is longer!

③If you want to block the GPS track, you need to choose a two-in-one jammer (low-cost 2G GPS jammer)) at least! Because when you only use the mini GPS jammer to block the GPS, it will be automatically activated by the built-in SIM card Realize GPRS GSM positioning.

2. After receiving the portable jammer with battery (desktop jammer without battery), it must be fully charged within 6-10 hours;

3. All antennas must be installed according to the markings (1-1 2-2 3-3 4-4 5-5 6-6 7-7 8-8 or GSM to GSM GPS to GPS…). More importantly, don’t open the shield without installing the antenna!

4. Interference range: position signal strength <= -75dBm. The interference distance will vary according to the signal strength and location. If you are close to the signal base station, the effect of the jammer will be very poor!
