Although it’s little in the dimension of size, but when talking about blocking ability, it’s almost all round against eavesdropping of various type.

As privacy is becoming increasingly important in today’s digital age, one way to protect our privacy is by equipping a UHF blocker, which is a useful tool that creates white noise to mask or distort conversations and other sounds around us.

By this principle, it becomes more difficult for those with complex purpose to eavesdrop on our conversations and invade our privacy to get some valid information.

How does RF Jammer protect you from being eavesdropped

Radio frequency blocking device SWU-PHDA-B1 is functioning by emitting a variety of sounds, such as white noise, pink noise, or random speech-like chatter, to create a sound barrier of 5~10 meters range which makes it harder for others to wiretap on our conversations.

This is particularly effective in those public areas, for there might be many prying ears trying to acquire our personal information or sensitive data.

By using this Anti Recording Jammer, our conversations will remain private and secure.
