Adapters Within Series Plugs, Straight, Clamp Type Receptacles, Straight, Square Flange, Male

UHF connectors were the first coaxial connectors developed and they are still widely used today. Intended for use with .199 to .432 diameter cables, they employ a screw type coupling mechanism and are recommended for use up to 300 MHz although they are usable to 500 MHz. They are not weatherproof. Many versions of these connectors are commercially available in various grades of quality and with many types of dielectrics including Rexolite, phenolic and Teflon, among others. All San-tron UHF connectors and adapters have Teflon dielectrics except for those adapters for which the military specifies Rexolite. Unless otherwise specified all San-tron UHF connectors are nickel plated and have silver plated center contacts. They are also available in other finishes such as silver or Albaloy.
