Product details

RF Connector for Tight Board-Edge Routing

The 221790-1: The PTFE dielectric keeps insertion loss to 0.3 dB across the band — clean enough for test equipment or antenna feeds where every tenth of a dB matters.

Right-Angle Mount for Space-Constrained Panels

Threaded fastening (the SMA standard coupling nut) gives a vibration-resistant mate that holds through 500 mating cycles.

Wide-Temperature RF Duty

The stainless steel body and gold plating resist corrosion in humid or salt-fog environments, and the PTFE dielectric holds stable impedance across the temperature swing.
