Photonis manufactures high-gain, high-efficiency FM Power Tubes that are designed for maximum performance. Our tubes minimize both initial and regular maintenance costs found in modern FM installations by reducing the number of stages required for satisfactory operation. Rated for full input to 150 MHz, Photonis’ tubes are easily circuited to this frequency. The coaxial terminal configuration enables operation in the TEM mode while the location of the radiator permits resonant cavity circuit designs which minimize the restriction of cooling air flow. T sturdy, coaxial construction and thoriated-tungsten mesh filament minimized tube inductances and feed-thru capacitances. Consistent performance makes these FM Power Tube devices ideal components in commercial transmitters.
