Transistordeelheter

Transistordeelheter is a type of broadcasting antenna used in early days of radio. The term is derived from the Dutch language, with "transistor" referring to the type of electronics used, and "deelheter" meaning "high-frequency portion carrier". It was designed to improve the efficiency and reliability of radio broadcasts in the mid-20th century.

The Transistordeelheter was developed as an alternative to conventional antennas and was used extensively by amateur radio operators and shortwave listeners. The device used a combination of transistors and tube amplifiers to amplify the weak signals received from distant radio stations. Its compact size and high-gain capability made it an attractive solution for mobile broadcasting applications.

Technical specifications of the Transistordeelheter include its frequency range, which typically spanned from high-frequency radio waves to ultra-high-frequency (UHF) signals, depending on the configuration. Its average current consumption is approximately 20 milliamps to 50 milliamps, and was usually powered by a 9-volt DC power source.

Variations of the Transistordeelheter were manufactured by several companies, primarily in Europe, including Philips and Eiko. These models had slight variations in design, specimen weight, and expected lifespan. The Transistordeelheter has since been largely superseded by solid-state transceivers and antenna technology improvements. However, the device remains an interesting piece of development history for those interested in the evolution of radio technology.
