4.3/10 Connectors

Amphenol RF 4.3/10 Connectors feature a small, weather-resistant design that offers voltage standing wave ratio (VSWR) performance up to 6GHz. When compared to 7/16 connectors, these devices are 40% lighter and provide greater PIM performance with separate electrical and mechanical contacts. 4.3/10 Connectors have an IP67 rating (unmated) and 50Ω nominal impedance. Amphenol RF 4.3/10 Connectors are ideal for low PIM and low attenuation applications such as distributed antenna systems (DAS), base stations, wireless infrastructure, telecom, and filters and combiners.
