What is GPS jammer? It is a GPS signal blocking devices, from the principle that is to send GPS Jammer and GPS signal wave signal wave overlap itself so that the original wave frequency to change the way to block the signal.
I'm curious how much can the Jammer shielding in the end range, is not there can be 1 km away, it would be too crazy
My friend had a Gps Jammer, when in use, similar to his car completely invisible, installed above the GPS completely lost their effect.
gps jammer installation is very simple, generally only need to plug in vehicle power adapter or car jack can be used.
