MFJ269 HF/VHF/UHF SWR Analyzer and Counter
Currently out of stockFeatures
Covers 1.8 to 170 MHz and 415 to 470 MHz. It includes all the features of the MFJ-259B, the worlds most popular SWR Analyzer plus much more! Large easy-to-read two line LCD display and side-by-side meters clearly display your information Built-in Ni-Cad/Ni-MH charger circuit, battery saver, low battery warning, smooth reduction drive tuning. Use as signal source for testing/alignment. Built-in CoaxCalculator -- calculates coax line length in feet given coax length in electrical degrees and vice versa for any frequency and any velocity factor (great for building matching sections and phasing lines) -- an MFJ-269. New 12-bit A/D converter gives much better accuracy and resolution than common 8-bit A/D converters. Super easy to use! Just set the bandswitch and tune the dial -- just like your transceiver.
1.8 to 170MHz range features
MFJ-269 gives you a complete picture of you antenna. Read antenna SWR and Complex Impedance 1.8 - 170 MHz. Built in frequency counter. Read Complex Impedance as a series of equivalent resistance and reactance (Rs+jXs) or as magnitude (Z) and phase (degrees). Also read parallel equivalent resistance and reactance (Rp+jXp). You can determine velocity factor, coax loss in dB, length of coax and distance to short or open in feet.
You can read SWR, return loss and reflection coefficient at at any frequency simultaneously at a single glance. Also read match efficiency. Also read inductance in UH and capacitance in pF at RF frequencies. You can measure SWR and loss of coax with any characteristic impedance from 10 to over 600 Ohms, including 50, 51, 52, 53, 73, 75, 93, 95, 300, 450 Ohms.
New 415 to 470 MHz Range features
Just plug in your UHF antenna coax, set the frequency and read SWR, return loss and reflection coefficient simultaneously. You can read coax cable loss in dB and match efficiency.
You can test and tune stubs and coax lines. You can manually determine velocity factor and impedances of transmission lines. You can adjust and test RF matching networks and RF amplifiers without applying power.
Has easy-to-read LCD logarithmic SWR bargraph and SWR meter for quick tuning.
