Product Description

Portable All in One Sz Vodasafe Handheld Sig-nal Blocker 21 Band with 21 Antennas Portable Sig-nal Jammer for 2g 3G 4G WiFi GPS Remote Signals
In an era where seamless wireless communication is ubiquitous, maintaining privacy, security, and undisturbed environments has become a critical need. Introducing the Sz Vodasafe P21 - a cutting-edge 21-band portable sig-nal jammer designed to deliver reliable, efficient, and versatile jamming performance across a wide range of radio frequencies. Whether for securing private discussions, eliminating disruptions in quiet spaces, or protecting against unauthorized tracking, the Sz Vodasafe P21 stands as a professional-grade solution tailored to meet global security demands for civilian use.
The Sz Vodasafe P21 is engineered to target and disrupt multiple wireless signals simultaneously, covering mobile networks (4G, 5G), satellite positioning (GPS, Glonass), wireless internet (WiFi), remote controls (RC, UHF), and tracking devices (Lojack). With 21 dedicated antennas (1W output power per band, total 21W), it ensures comprehensive coverage while allowing independent control of each band - a feature that lets users customize jamming based on specific needs without affecting other frequencies.
Crafted for portability and durability, the jammer features a robust metal aluminum case (black color) paired with a green holster for easy carrying, weighing only 1.6kg (main unit, excluding antennas) and measuring 220 x 140 x 70mm (main unit dimensions). This compact design makes it ideal for both indoor (meeting rooms, libraries, theaters) and outdoor (public checkpoints, temporary event venues) use.
Frequency Bands: Tailored for Global Regions
The Sz Vodasafe P21 is available in two region-specific variants to ensure compatibility with local frequency standards: Sz Vodasafe P21-E (Europe) and Sz Vodasafe P21-A (America). Each variant targets the most commonly used wireless bands in its respective region, delivering precise and effective jamming.
