30W Each Band Prison Signal Blocker/Waterproof Cell Phone Signal Blocker




The Six-Way Prison Signal Shield is a versatile signal blocker that can be installed indoors and supported outdoors because its enclosure is waterproof, with a built-in fan and a good cooling system. The frequency segment can be customized. Its normal frequency setting is 2G3G4G+Wi-Fi or 2G3G4G+Gps. The output power of each channel is 10-30W, and the total output power is 180W. The shielding range of this prison signal shielding device can be Up to 100 meters, and its configuration antenna can also be selected according to your needs. There are several types of antennas. One is a directional antenna. The coverage of this type of antenna is relatively long, and the signal can be covered for the orientation you need, rather than covering the signal centered on a certain point. Another type of antenna is a fiberglass omnidirectional antenna that radiates a signal outward at a certain point. The range in which the gain of the antenna is also different is also different. These are all you can customize as needed. Please contact us if you need it.
