The eavesdropping transmitter operates at a high and completely discrete frequency in the UHF band.
The eavesdropping transmitter operates at a high and completely discrete frequency in the UHF band. The transmitting toss is controlled by saw resonator. The device is equipped with a special knowles microphone with a sound range of up to 15m -25m. You get the cleanest audio from the eavesdropping room in hifi !!!
The device is fundamentally different from the VHF eavesdropping devices, especially with a short but precisely tuned helical antenna. In practice, this means that the energy from the power supply cell is more efficiently used, while the transmitter's range is significantly greater than that of the VHF transmitter, the same power.
