UHF audio transmitter with double room-telephone listening function. WFM modulated transmission and telephone line power supply

This multifunction telephone bug is ideal both for telephone and environmental wiretapping with related radio transmission. The device consists of a very high sensitivity extended microphone, an external antenna and flexible cables for connection to the telephone line. The transmitter connection is in parallel on the analog telephone line acting at the same time as a direct power source.

The ENSTK-050 audio transmitter works normally as a room covert listening device, but when the telephone handset is lifted the wiretapping function activates. On hanging up, you go back to environmental listening mode.
