A professional PLL UHF CRYSTAL CONTROLLED RECEIVER Version 2, and its design differs from Ver. 1 receiver which may look alike. Due to its special design is the most stable, sensitive and powerful you may find. It is supplied with an additional sensitive RF stage, an on/off LED and the most important: a detachable anttena .
This feature is very important when you wish to listen from a car. The antenna can be removed, attached to an BNC cable, and this way only the small antenna is outside the car.
All our Crystal Controlled UHF transmitters (phone line transmitters, phone "adapters" transmitters, Mains (110V / 220V) transmitters, VOXes and room transmitters will match the receiver frequency.
This model has excellent reception circuit and great sound quality.
The high quality external earphones produce 80mW of crisp, clean audio power, allowing you to hear all the details of conversations.
It can be connected to a recorder and earphones at the same time.
This high quality receiver costs less than any Narrow-band scanner receiver or most of other professional receivers and it matches perfectly the frequency for receiving signals from our professional transmitters.
This model was thoroughly tested with our transmitters in various conditions and we absolutely recommend it for use.
The PLL UHF CRYSTAL CONTROLLED RECEIVER can be used in a room or business, indoor or outdoor.
