UHF PLL Receiver, NFM 433 MHz improved version

A revolutionary design in the UHF room bugging and spying UHF NFM Receivers
Used for conversation picking up conversations, the PLL Receiver employs an extra high sensitivity circuit which allows the user to pick up RF NFM Transmitters from up to 800+ meters away. The PLL Receiver employs a state-of-the-art surface-mount technology, making it the most effective wireless audio receiver of its kind. The stability and efficency of the UHF PLL Receiver V2 is huge compared to other receivers.
We've designed it especially for this purpose. It draws 5 times less current than any other similar 9V receiver, and at the same time, the stability is not affected. It is crystal controlled.

Features:

1. The device's dimensions are very compact. Easier to conceal.
2. Our equipment weight is less than 60% of other equipment.
3. The receiver easily fits in a shirt pocket, so you won't have to hold it in your hands.
   
4. The antenna is thinner, shorter and detachable - less observed. It can be used with an external antenna - for inside car surveillance.
   
5. 5 times less current drawn from the battery, so it lasts a prolonged time.
6. Our receivers are more sensitive than any others.
7. High-quality precise PCB.
8. High-quality golden cover of contact plates.
9. Active and passive elements from leading worldwide brands.
