MFJ-269C SWR Antenna Analyzer 530 KHz - 230 / 415-470 MHz Continuous Coverage The MFJ-269C is a compact battery powered RF impedance analyzer. It combines five basic circuits; a variable oscillator, frequency counter, frequency multiplier, 50-ohm RF bridge, twelve-bit A-D converter, and a microcontroller. Together, these circuits perform a wide variety of useful antenna and RF impedance measurements including coaxial cable loss and electrical distance to an open or short. Built-in frequency counter, Ni-MH/Ni- CD charger circuit, battery saver, low battery warning and smooth reduction drive tuning. Large easy-to-read two line LCD screen and side-by-side meters clearly display your information. Read SWR, return loss and reflection coefficient at any frequency simultaneously. Although mainly designed for analyzing 50-ohm antenna and transmission line systems, the MFJ-269C also measures RF impedance from a few ohms to several hundred ohms. An easy-to-access user-controlled Zo setting in the Advanced function menus facilitates 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 MFJ-269C also functions as a non-precision signal source and frequency counter.
