Introduction

The SARK-110 is a completely new design concept for an Antenna Analyzer. This is a truly pocket size device, so you can take it anywhere. It offers a gorgeous 3” high-resolution, active-matrix color display that allows information-rich diagrams. The user interface has been designed to be intuitive and easy to use. On-screen menus provide user guidance and the operation is mainly controlled by the two navigation keys. The graphical impedance displays provide a quick view of the antenna impedance characteristics on a user selected frequency range.

Melchor Varela (HAM call sign EA4FRB) is the designer of Sark-110. He is from Spain. Seeed started cooperation with Melchor in 2011. At the end of 2014, Melchor decided to develop a new version with an improved enclosure design and other enhancements, including the provision for a future two-port analyzer. In addition, Seeed worked with Melchor to design a new Protective Casing since it was an accessory wanted by customers.
