JOHNSON RF CONTACTORS The 145-100 and 145-200 contactors are especially de-signed for high voltage radio frequency switching and dc voltage switching in high voltage rectifier circuits. They require no holding power and will operate with a momen-tary application of voltage.

Standard contactors are supplied with four auxiliary switches: two normally-closed for control of solenoid voltage and two normally open for operation of signal lamps or other related functions. Solenoids are wired for 220 v, 50-60 Hz, or can be strapped for 110 v.

LTU ANTENNA TUNING IJN1TS

The Collins LTU series of antenna tuning units are custom-designed for each individual application and are available in either 1 kW, 5 kW, 10 kW, or 25 kW power ratings. They are mounted in a weatherproof aluminum housing with full-width wraparound door. A window facilitates reading of the antenna current meter. The meter is actuated by an external operating handle. The custom-designed fuli "T" network uses high quality, conservatively rated components. A silver-plated bus, located at the bottom of the housing provides a ready Iow resistance connection to the antenna ground system. A special terminating connector allows connection to any coaxial cable with a one-inch outer conductor diameter or smaller. Other sizes may be accommodated as required. The housing is finished with light-colored paint to minimize internal temperatures; weather-proof screened vents allow air circulation.
