The SARK-110 series of antenna analyzers are pocket size, multipurpose precision instruments capable of analyzing antennas or networks, generating or detecting signals and performing Time-Domain-Reflectometry (TDR) measurements on transmission lines.

Typical applications include antenna verification and adjustment, impedance matching, component testing, cable fault location, coaxial cable parameter measurement, and coaxial cable cutting at precise electrical lengths. As a signal generator, they are ideal for receiver calibration, sensitivity testing and signal tracing.

The analyzers have full vector measurement capability and accurately solve the resistive, capacitive and inductive components of a load. The accuracy is excellent over a broad range of impedances and rivals any of the competitive devices in the market.

The SARK-110 series is designed for standalone operation but can be controlled from your desktop computer using SARK Plots for Windows and from your tablet or smartphone using SARK Plots for Android via USB or short-range Bluetooth Low Energy (SARK-110-ULM only).

The analyzers use an internal flash disk of 2MB for the storage and retrieval of measured parameters, screenshots, analyzer configuration and firmware updates. This disk can be accessed through USB, so the measured parameters can be downloaded to a computer for analysis using the ZPLOTS spreadsheet program or the SARK Plots software.

The SARK-110 is upgradeable. As necessary, new firmware versions are available on this site for free.


The SARK-110 is the high-end, high-accuracy model. It features a 3" high-resolution colour display for information rich diagrams and an intuitive user interface through two navigation switches and four buttons. The measurement frequency range is between 0.01 and 230 MHz. As a signal generator, it outputs a sinusoidal wave signal with a programmable power level from -73 to -10 dBm. The built-in battery lasts up to 2.5 hours on a single charge. An optional protective rubber case is available.


The SARK-110-ULM is the entry-level model. It features a graphical display and an intuitive user interface through nine front buttons. The native measurement frequency range is between 0.1 and 160 MHz, but it operates up to 1 GHz with reduced performances. As a signal generator, it outputs a square wave signal with two selectable power levels. In addition to the USB interface, it includes a short-range Bluetooth Low Energy interface. The built-in battery lasts up to eight hours on a single charge.
