Portable anti GSM jammer device blocks bluetooth with 8 high-gain omnidirectional antennas (16W)

First glance, eight antennas may seem like a simple design choice. However, these 8 high-gain omnidirectional antennas actually provide 360-degree signal coverage, with each antenna representing an independent frequency channel with an output power of 2W (the total output power is 16W).

Furthermore, the desired frequency band can be selected based on the corresponding DIP switch, without forcing each channel to operate continuously, enabling the P-B8 to handle multiple signal ranges within a single device.

The mobile cell jammer supports interference across:

• CDMA850: 850-960 MHz
• PCS/PHS: 1805-1880 MHz
• 3G: 2110-2170 MHz
• 4G 700: 700-803MHz
• 4G 2600: 2496–2690 MHz
• 5G Low-Band: 617–698 MHz
• 5G 1500: 1427-1518MHZ
• WiFi 2.4GHz: 2400-2500MHz

The jamming range is 10-20m, through our testing, this GSM jammer can interfere to a distance of 20 meters without any building obstruction.

Handheld jamming devcie often face the same challenge — limited space and heat buildup. The cellular phone jammer solves this with a dual cooling structure.

Dual integrated cooling fans and large ventilation grilles are installed on both sides of the equipment to assist in heat dissipation. This detail may seem small, but it directly affects long-term operating stability.

After all, a portable signal blocking equipment is not only judged by what it can do in the first few minutes, but also by how consistently it performs during continuous operation. It also comes with a nylon outer shell.

Not all application scenarios have wall sockets nearby.The bluetooth blocker includes a built-in 7.4V 4600mAh rechargeable battery, providing approximately 1.5 hours of continuous operation.

When extended use is needed, the included power options make switching between locations easier:

• AC 110–240V input with DC 12V adapter
• Vehicle charger for mobile power supply

This combination gives the network blocker the flexibility of a portable unit while keeping the convenience of a fixed-power device.
