TRANSMITTER BUILT FOR QUALITY &T£s BC-5P 5KW Gates engineers have created a dual feature in the BC-5P AM Transmitter to save broadcasters dollars and engineering time. Because of possible future FCC regulations pertaining to harmonic radiation and bandwidth, the PA tank circuit is built into a completely enclosed aluminum compartment. The output circuit, which is a full tee network enclosed in its own shielded compartment, is a natural repellent of spurious radiation. By isolating these sections in two shielded compartments, 100% air cooling of inductors, capacitors, choke coils and tubes, along with maximum harmonic reduction, has been brought about. This means longer component life through lower operating temperatures and cleanliness. BROADCASTERS WANT THE FINEST TRANSMITTER THAT THE INDUSTRY CAN PROVIDE, AND ONLY ONE TRANSMITTER IN THE 5 KW FIELD IS PACKED WITH SUCH OUTSTANDING QUALITIES — THE GATES BC-5P .... HIGHEST STANDARD OF PERFORMANCE, MUCH LESS SPURIOUS RADIATION, LOWEST COST TUBE COMPLEMENT, AND THE LOWEST PRIMARY POWER CONSUMPTION OF ANY 5 KW AM BROADCAST TRANSMITTER MANUFACTURED TODAY. COMPARE EVERY FEATURE . . . . AND YOU WILL SEE THAT THE BC-5P IS SUPERIOR BY EVERY MEASURE. Contact your nearest Gates sales engineer or write the Gates Radio Company today for full details.
