This kit attaches in series to one of your phone lines. When there is a signal on the line (that is, when you pick up the handset) the circuit will transmit the conversation a short distance. The radio signal will radiate from the phone line itself. It is a passive device - there is no battery. It uses the signal on the signal on the phone line for power.
Miniature transmitter attaches to the phone line and transmits the conversation. Transmits 200 yards and more in most installations. Tunable to clear spot on the FM band of your radio.
