Mfj-219B uhf swr antenna analyzer 410 to 460-mhz
MFJ-219B UHF SWR ANTENNA ANALYZER 410 TO 460-Mhz
THIS IS IN GREAT CONDITION. WORKS FINE. COVERS 410 TO 460-MHz WORKS WITH TWO 9-V INTERNAL BATTERY'S. PLEASE SEE ALL THE PHOTOS. THIS IS THE UNIT AND THE BOX..
Just plug in your antenna coax, set the frequency and read SWR!
The MFJ-219 Antenna SWR Analyzer covers 420 to 450 MHz. You can select any desired frequency range for tuning.
Examples: Tune from 420 to 450 Mhz, etc.
Tuning knob has a built-in 10:1 vernier reduction drive for extra smooth precision tuning.
You can use the MFJ-219 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.
