This is a very small transmitter considering the power level, and it is PLL controlled.  The transmitter has four channels which are set via two dip switches on the face of the unit.  The built in microphone automatically adjusts it's volume based on the ambient noise.  Best of all, the unit operates at a core voltage of 5v, making it incredibly easy to integrate with the Panasonic KX121 Color CCD camera available here.
This picture shows a size comparison between the transmitter and the Panasonic KX121 Color CCD camera (not included)
Both the receiver and transmitter come with dipole antennas. The antennas unscrew easily to allow you to use different antennas.  Transmitter has a built in microphone. Transmitter connections are made via a tiny four pin connector for which no mate is included.  When we implement this transmitter ourselves we simply cut the header off and solder directly to the wires.

Excellent performance in a tiny package

Everything about our new equipment is tiny, from the compact receiver that will fit in the palm of your hand, to the tiny transmitter that will balance on your thumb! Please note that the receiver case style may vary, but it is is the same dimensions shown here.

Power supply is priced separately so that folks who plan on running the receiver (which runs on 12v) don't get a wall wart they don't need..
