Abstract:
A portable advertising sign is positioned in proximity to a street and includes a message board. A low power transmitter is physically secured to the sign and generates a modulated RF output signal at a predetermined frequency within the broadcast band. An antenna colocated with the sign is coupled to the transmitter and radiates the transmitter output signal. A cassette tape player is positioned in a secure area physically spaced apart from the sign by a substantial distance and includes a colocated power supply for supplying a DC voltage. A cable conveys the audio output signal from the tape player and the DC voltage from the power supply to the transmitter. The sign message board displays the operating frequency of the transmitter to vehicles passing by the sign.
