Do wireless GPS signal jammers really have no antennas? In fact, the wireless GPS jammer refers to the wirelessly transmitted GPS signal jammer, which actually has an antenna. Antennas are generally divided into two types: external whip antennas and built-in booster antennas.
1. What is an external whip antenna?
The external whip antenna refers to the GPS signal jammer equipped with external antennas. These external antennas are locked on the machine, and the machine that can rotate through 180° is called whip antenna.
2. What is the built-in gain antenna?
A booster antenna refers to an antenna that is set inside the device, the machine needs to be turned on to see the antenna, and it cannot be rotated, but an antenna that can cover 360° azimuth is called a booster antenna.
Everyone has a concern about the use of GPS signal jammers: will there be radiation? Is there any harm to the human body?
In fact, as long as it is an electronic product, it will more or less generate radiation. However, the country has stipulated a range for the radiation of mobile phones, so the radiation generated by the GPS signal jammer is lower than the range stipulated by the state, and the GPS signal jammer is not like a mobile phone, it needs to be placed next to the ear every day, so it is harmful to the human body. The damage is very small, you can rest assured to use.
