The Anritsu S818A Site Master is a synthesizer-based, handheld cable and antenna analyser designed for field professionals who install, maintain, and troubleshoot wireless communication infrastructure. Operating from 3.3 GHz to 18.0 GHz, it delivers accurate, repeatable measurements of antenna systems, coaxial feedlines, and waveguide components. The instrument is engineered for rugged field use with a lightweight, battery-operated design that allows technicians to work at tower base level while the built-in Distance-to-Fault (DTF) function compensates for cable insertion loss.

Option 5 adds the Waveguide Analyser capability, enabling DTF measurements on both coaxial and waveguide media. The S818A is widely used in the installation, commissioning, and periodic maintenance of cellular base stations, microwave links, and other RF transmission systems.

Key Features:
- Handheld, battery-operated, synthesizer-based design
- Built-in Distance-to-Fault (DTF) using inverse Fourier Transform of swept frequency data
- Option 5: Coax and Waveguide Analyser with Tune Mode for waveguide component alignment
- Saves up to 200 measurement traces in non-volatile memory
- Multilingual user interface
- Superior immunity to interfering RF signals
- 517 data points for long-range fault location
