The Anritsu Site Master S251C is a rugged handheld two-port cable and antenna analyzer designed for installation, maintenance, and troubleshooting of wireless communication systems. Covering the 625 MHz to 2500 MHz frequency range, this instrument enables accurate measurement of return loss, VSWR, cable loss, and distance-to-fault (DTF) on RF feeder lines and antenna systems.
With its built-in RF source, high immunity to live-site interference, and optional bias tee, the S251C supports advanced two-port measurements such as insertion loss, gain, and antenna isolation. Its menu-driven interface, large high-resolution display, and durable field-ready design make it ideal for technicians performing tower-top and ground-level verification tasks.
