USB Cable + UHF transmitter in one

It looks just like any other cable which can be plugged into a USB port for any kind of hardware connection. But this USB cable is also a UHF transmitter, so it does double duty. A super sensitive microphone can also be found in there allowing the cable to be used for recording conversations and listening in from a 200 - 500 meter range.

Gain control is handled automatically which allows you to hear things from the microphone when it’s up to 40 feet away from the subject. With it being USB and connected to a USB port the cable requires no extra power. The cable is 6 feet long and works in the 433-434 MHz range.

The cable connects to any USB 1.1 or 2.0 interface and simply works out of the box.
