DESCRIPTION

SET PLL UHF CRYSTAL CONTROLLED RECEIVER AND MAUHF 110V or 220V AC BUG TRANSMITTER QUARTZ CRYSTAL STABILIZED


This is the best set of the professional AC Mains operated (110V - 220V) transmitter-receiver on the UHF band.
It can cover an incredible large area, and due to its special design is the most stable and powerful you may find.
The Mains AC 110V - 220V NFM SET uses high quality Japanese and U.S components and supplied with a super sensitive RF stage.

This professional transmitter doesn't use any battery. It is connected directly to the AC Mains electricity 110V or 220V . A special audio filter make it more sensitive than ever to human voices.

The Miniature UHF transmitter is designed for use in a property or business place indoor or outdoor. This AC transmitter will transmit conversations to a distant receiver.
It has an exceptional audio quality.
The transmitter's size is so small, that it may be concealed it imperceptible in any secret place.

The sensitive receiver is adjusted to 433.xxx MHz and stabilized by Quartz, fixed frequency.
We are adjusting each set to 100% matching frequency. One of the unique receiver features - listening to the conversation and recording at the same time, if it is connected to a recorder.
The estimated distance is from 200m in urban areas and up to 400+ meters on line of sight.
