The MFJ-259B Antenna Analyzer has solidified its reputation as the world's most popular SWR/RF analyzer, now enhanced with features that provide even greater value for users. This versatile device offers a comprehensive assessment of antenna performance, allowing operators to measure SWR and complex impedance across a broad frequency range from 1.8 to 170 MHz. Users can view complex impedance as series resistance and reactance (R+jX) or as magnitude (Z) and phase (degrees), making it easier to understand the antenna's characteristics.

In addition to SWR readings, the MFJ-259B enables users to determine various critical parameters such as velocity factor, coax cable loss in dB, and the length of the coax. It also provides the distance to a short or open circuit in feet, enhancing troubleshooting capabilities. The analyzer displays return loss and reflection coefficient at any frequency simultaneously, ensuring that all relevant data is available at a glance. Furthermore, it measures inductance in microhenries (µH) and capacitance in picofarads (pF) at RF frequencies, making it a valuable tool for amateur and professional radio operators.

The MFJ-259 B's user-friendly design features a large, easy-to-read two-line LCD screen alongside side-by-side meters for clear data presentation. With a built-in frequency counter, Ni-Cad charger circuit, and battery-saver functionality, this analyzer is designed for convenience and efficiency. The smooth reduction drive tuning simplifies operation; users simply set the band switch and tune the dial, making SWR and complex impedance readings instantaneous. The MFJ-259B is not just an analyzer but an essential tool for anyone serious about optimizing their antenna systems.

Used items may exhibit minor imperfections such as scratches, dents, or discolouration, which are common due to previous usage.
