RF detectors are devices designed to detect and locate radio frequency (RF) signals, commonly used for identifying the presence of wireless devices, hidden transmitters, or surveillance equipment. However, a common question is, do RF detectors block signals? The primary function of an RF detector is to monitor and detect RF emissions rather than block them. In other words, RF detectors are passive devices that scan the environment for RF signals but do not interfere with or block the signals themselves. To block RF signals, a different type of device, such as an RF jammer or signal blocker, would be required. RF detectors are useful for identifying unauthorized transmissions, but they do not have the capability to stop the signals from being transmitted. Therefore, while RF detectors play a key role in signal detection, they do not serve the purpose of signal blocking.
