The 083-878 is a rear mount bulkhead jack from the Amphenol RF UHF connector series, designed for low-frequency applications. This connector features a nickel-plated body and a silver-plated contact, providing a durable and reliable connection. It utilizes a 5/8-24 threaded coupling for rugged mating and is designed for use in systems from DC to 300 MHz. Because these are general-purpose, low-cost connectors, the impedance is variable. It is ideal for a variety of commercial applications such as antennas, public address systems, and CB radios.
