It draws considerably less current than any other similar 9V receiver, and at the same time, the stability is not affected. We've designed it, especially for this purpose. The area of the UHF PLL Receiver is huge compared to other receivers. The PLL Receiver / Transmitter set employs state-of-the-art surface-mount technology, making it the most effective wireless audio transmitter of its kind. Used for picking up conversations from our medium-power transmitters, the PLL Receiver employs an extra high sensitivity circuit that allows the user to pick up RF NFM Transmitters from up to 300+ meters away. It has a high-sensitivity input circuit that allows the user to hear the small FM transmitter from up to 300 meters away in metropolitan environments (Line Of Sight, depending on terrain). The PLL UHF crystal-controlled receiver may be utilized in a room or office, as well on any part of your living place. It comes with a sensitive RF input, fitted with earphones, it becomes one of the greatest receivers for our surveillance bugs and listening devices. It is extremely sturdy, sensitive, and strong due to its unique design.

However, the higher installations are increasing the distance.Ī quartz crystal listening device designed specifically for our devices stabilizes the PLL UHF crystal-driven receiver. It may be hidden within any non-metallic object actually in any place. The listening device is a strong audio espionage transmitter with a minuscule microphone and a flexible antenna, that is ideal for covert activity, in a variety of properties and locations.įrequency drift is prevented and the frequency is stabilized. Only high-quality components are used in this set, and one of the receiver's unique characteristics is the ability to listen and record simultaneously when attached to a recording device. We're tweaking each set to a frequency of 100 percent matching. This set incorporates the UHF transmitter's compactness and efficiency (using 3-6V batteries) with the sophisticated UHF-433 PLL receiver Ver. SET UHF Receiver and Transmitter 3 to 6V NFM
