- As we all know, full-band jammers, with their advantages of high efficiency, stability, reliable quality, and strong interference, play an important role in various places that require signal shielding, such as examination rooms, party and government agencies, large enterprises, etc. Now many families are trying to So that children can concentrate on learning, they will also choose a full-band jammer with better performance. So how to choose a full-band jammer?
1. According to signal strength
The selection of a full-band jammer should also be determined based on the signal in the environment. If the signal at the site is very strong, such as an area relatively close to the signal base station, or if there are signal base stations and amplifiers installed on the roof of the community, then the jammer must be selected. A very capable full-band jammer. Generally speaking, a full-band jammer salesperson with good service will help you choose a suitable full-band jammer based on signal strength.

2. Look at the shielding range and power
Generally speaking, the shielding range of a full-band jammer is proportional to its power. That is to say, the greater the power, the greater the shielding range. For low-power full-band jammers, its shielding range is generally dozens of square meters. Some parents I would choose to install this kind of device in my own room, and the high-power shielding distance is several hundred square meters. This kind of device is especially suitable for large examination rooms and large enterprises.
3. Look at the location of the antenna
Generally speaking, full-band jammers can be divided into external antennas and built-in antennas. Since the antenna is external and extends outward, the former occupies a larger space compared to full-band jammers with external antennas. However, its antenna effect is much more stable, its radiation distance is farther and longer, and its coverage area is larger, so external full-band jammers are used relatively more.
It can be seen that to choose a suitable full-band jammer, we can judge based on the signal strength of the venue, the power of the jammer, and whether the antenna is external or built-in. Of course, we can also judge based on the power supply method of the full-band signal blocker. To choose from, there are generally handheld ones with built-in lithium batteries, as well as voltage power supply forms with various voltage ranges. - Going people
