Quick Overview

Graphical Antenna Analyser
Excl. Tax: £394.12 Incl. Tax: £472.95


The MFJ-225 has got all functions of a standard analyser plus a variety of new functions, such as built-in LC display, 2 port VNA and USB port. The MFJ-225 does not require calibration (self-calibrating)! Very easy to use. All functions are described in the included English manual. Two antenna analysers in one The MFJ-225 is a complete, self-contained analyser that is battery-powered and thus can be installed directly at the antenna. Connect the device to a PC and use the IG-mini VNA freeware to create a fully-fledged 2-channel VNA and do extensive data analysis. You can also print graphical curves in addition to your numerical results. View more Thanks to the built-in, illuminated 3″ graphic display, you will always have all the values in view. In addition to the presentation of discrete values, the SWR can also be plotted graphically as a curve. Other important displayed values are Impedance, V/R ratio, phase angle. Set center-frequencies with a knob on the side of the MFJ-225 and read the curve in full screen mode on the display. Frequency range from 1.5 to 179.9 Mhz The MFJ-225 analyser covers the entire frequency range from 1.5MHz to 179.9 MHz continuously with the help of an integrated DDS-VFO with 1 khz resolution, so all mechanical elements like switches or controller are no longer necessary. The adjustment is done by an optical encoder. Built-in signal generator The MFJ-225 uses a built-in signal generator with -5dBm power output to test several components such as mixer, amplifier, filter etc. The signal has a good suppression of harmonics of -50dBc and provides for excellent test results. Versatile power supply For operation of the MFJ-225 you can use 4 AAA (rechargeable or Alkaline) batteries. These are installed inside the device. With a 12V socket attached on the side, you are even able to recharge the batteries. A LED light shows the charging status. A USB cable does also function as a power supply for the MFJ-225 when connected to a PC. What is the MFJ-225 able to measure •SWR (1:1 to 9.9:1) •Complex impedance (R + jX) •Return loss (RL, 0 - 30dB) •Phase (0 - 180°) •Capacity (0 - 9999pF) •Inductance (0.1 - 80µH) •Cable length (0.5 - 45m) •Cable loss (0 - 30dB)
