Just plug in your antenna coax, set the frequency and read SWR!
Easy-to-read LCD displays frequency and SWR and has a logarithmic SWR bargraph for precision tuning. Two line high contrast LCD has 32 huge 1/4 inch characters.
The MFJ-229 Antenna SWR Analyzer covers 270 to 480 MHz. You can select any desired frequency range for tuning.
Examples: Tune from 280 to 295 MHz, 320 to 350 MHz or 400 to 450 Mhz, etc.
Tuning know has a built-in 10:1 vernier reduction drive for extra smooth precision tuning.
You can use the MFJ-229 Antenna SWR Analyzer to adjust dipoles, verticals, yagis, quads and other antennas and determine their SWR, resonant frequency, and bandwidth.
You can test and tune stubs and coax lines. You can determine velocity factor. Impedances and estimate losses of transmission lines.
You can adjust and test RF matching networks and RF amplifiers without applying power.
Use as a signal source for testing and alignment.
Built-in "N" connector includes free N-to SO-239 UHF adaptor. has Battery Check and Power Saving feature. For 50 Ohm systems. Use 10 AA batteries or 110 VAC with MFJ-1312D, $14.95. 3 3/4W x 6 1/2H x 1 3/4D in.
