Covers 1,8-170 MHz and 415-470 MHz (Same as MFJ-259B + UHF)
Super easy to use! Just set the bandswitch and tune the dial – just like your transceiver.
Large easy-to-read two line LCD display and side-by-side meters clearly display your information.
Easy-to-read LCD logarithmic SWR bargraph and SWR meter for quick tuning.
Built-in Ni-Cad/Ni-MH charger circuit, battery saver, low battery warning, smooth reduction drive tuning.
Can be used as signal source for testing/alignment.
Built-in CoaxCalculatorTM – 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)
12-bit A/D converter gives much better accuracy and resolution than common 8-bit A/D converters
Built in frequency counter
Can be used to:
Read Complex Impedance as series equivalent resistance and reactance (Rs+jXs) or as magnitude (Z) and phase (degrees)
Read parallel equivalent resistance and reactance (Rp+jXp)
Determine velocity factor, coax loss in dB, length of coax and distance to short or open in feet
Read SWR, return loss and reflection coefficient at any frequency simultaneously at a single glance. Also reads match efficiency.
Read inductance in mH and capacitance in pF at RF frequencies.
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
Test and tune stubs and coax lines. You can manually determine velocity factor and impedances of transmission lines.
Adjust and test RF matching networks and RF amplifiers without applying power.
Adjust UHF dipoles, verticals, yagis, quads and other antennas and determine their SWR, resonant frequency and bandwidth.
Built in "N" connector Free N-to-SO-239 adaptor.
Use 10AA Ni-MH or Ni-Cad or alkaline batteries (not
NOTA : I use this SWR analyzer since April 2004.
