MFJ 269 PRO Amateur, Commercial and CB Antenna Analyzer

Featuring extended coverage in the UHF band from 430MHz to 520MHz and commercial grade cabinet to protect knobs.

With a 1.8 to 170MHz & 430 - 520MHz frequency range the MFJ-269PRO gives you a complete picture of your antenna. Read antenna SWR and complex impedance from 1.8 - 170MHz and 430 - 520MHz. This unit has a built in frequency counter. Read complex impedance as series equivalent resistance and reactance (Rs+jXs) or as magnitude (Z) and phase (degrees). Also read parallel equivalent resistance and reactance (Rp+jXp) -- and MFJ-269 exclusive!

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 and 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 -- an MFJ-269 exclusive!

New 415 to 470 MHz Range features on 269 Version. Pro version includes coverage from 430-520. 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.
