-- Fairview Microwave is now introducing 30 watt UHF Male Terminations. UHF is commonly referred to as PL-259 for Plugs and SO-239 for Jacks or Sockets. The connector is mainly used in RF applications but can be commonly found in the video industry for radar applications. Although the UHF connector has been mainly replaced by many other connectors such as the N or BNC connector they are still used in radio applications. It's fairly popular among amateur radio enthusiasts. UHF connectors were very popular for the input and output of composite video signals for older video equipment during the late 1970s and earlier. The UHF connector also has a nomenclature of the Amphenol connector because it was invented in the 1930s by an Amphenol engineer by the name of E. Clark Quackenbush. It's initial purpose was for low frequency systems from 0.6 to 300 Mhz but that frequency band has since been increased in the recent generations. A benefit of the UHF interface is it's large size threading helps in it's rugged design and helps keep a low end cost. The dummy load has a frequency range of DC to 512 Mhz and can nominally handle 10 watts but can handle 30 watts for up to 1 minute. Fairview Microwave's 30 watt UHF Male Termination has a part number of STT0512. STT0512 has a VSWR of 1.25 and a 50 ohm non inductive resistor. The product is a little over 3 inches long.
