HF/VHF/UHF SWR Analyzer MFJ-269

MFJ-269 HF/VHF/UHF SWR Analyzer

The MFJ-269 RF analyzer is a compact battery powered RF impedance analyzer. This unit combines five basic circuits: a variable oscillator, frequency counter, frequency multiplier, 50 ohm RF bridge, a twelve-bit A-D converter, and microcontroller. This unit performs a wide variety of useful antenna and RF impedance measurements, including coaxial cable loss and electrical distance to an open or short.

Primarily designed for analyzing 50 ohm antenna and transmission line systems, the MFJ-269 also measures RF impedances between a few ohms and several hundred ohms. An easily accessed usercontrolled Zo setting in the ADVANCED function menus allows changing SWR and other SWR functions (i.e. return loss, reflection coefficient, match efficiency, etc) to any normalized impedance value between 5 and 600 ohms.

The FREQUENCY switch selects the following internal oscillator frequency ranges. (A small overlap outside each range is provided): 1.8 - 4 MHz, 4 - 10 MHz, 10 - 27 MHz, 27 - 70 MHz, 70 - 114 MHz, 114- 170 MHz, 415-470 MHz.
