MFJ 259B Antenna Analyser

MFJ-259B antenna analyserWithout doubt, the most indispensable piece of equipment to have in your toolkit when playing around with wire (or indeed any other type of) antennas is an MFJ 259B antenna analyser.

This clever piece of kit can perform many functions and makes tuning the antenna a breeze.

Not only can you use it as a “smart” SWR meter, it can also be used as a frequency counter, RF signal generator, RF resistance and Reactance Analyser, Coax Analyser, Capacitance and Inductance Meter.

It can also read inductance in UH and capacitance in pF at RF frequencies.
The large easy-to-read two line LCD screen and side-by-side meters clearly display the information.

The MFJ 259B gives you a complete pictures of your antenna’s performance.
It’s easy to read Complex Impedance as series resistance and reactance (R+jX) or as magnitude (Z) and phase (degrees).

You can determine velocity factor, coax cable loss in dB, length of coax and distance to a short or open in feet – very handy for finding cable faults on long runs.

Super easy to use! Just set the bandswitch and tune the dial. SWR and Complex Impedance are displayed instantly!
