What is the reason why the signal jammer does not work or is ineffective?
There are many jammers on the market today, but many customers often encounter situations where the jammer does not work or is less effective because they do not know how to use it. Do you know what causes this phenomenon?
1. It is very important that you order a suitable jammer according to your needs.
If you want to block mobile phones, then you must choose a 2G 3G 4G full-frequency signal jammer. At this time, you must consider whether to add additional functions such as GPS (satellite positioning) or WIFI (wireless Internet access)!
Choose the appropriate power supply: the portable shield has low power and is easy to heat, while the desktop shield has high power and good heat dissipation! The desktop shield has a longer shielding range!
If you want to block gps tracks, you need to choose a 2-in-1 jammer (low-price 2G GPS blocker) at least! Because when you only use the mini gps jammer to block GPS, it will automatically activate through 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). What's more, don't turn on the jammer without an antenna installed!
4. Interference range: location signal strength <= - 75dBm. Interference distance will vary based on signal strength and location. If you are close to a signal base station, the jammer will be less effective!
