Description

Our tube minimizes both initial and maintenance costs in modern FM installations by minimizing the number of stages required for satisfactory operation. Rated for full input to 150 MHz, the tubes are easily circuited to this frequency. The coaxial terminal configuration enables operation in the TEM mode. The configuration combined with the location of the radiator permits resonant cavity circuit designs which minimize restriction of cooling air flow. Their sturdy, coaxial construction and thoriated-tungsten mesh filament minimizes tube inductances and feed-thru capacitances. Consistent performance makes these FM Power Tube devices ideal components in commercial transmitters.
