BRAND NEW - MFJ-259B ANTENNA ANALYZER 1.8 to 170 MHZ
The World's most popular SWR/RF analyzer just got incredibly better and gives you more value than ever! MFJ-259B gives you a complete picture of your antenna's performance. You can read antenna SWR and Complex Impedance 1.8 to 170MHz
Here's what you can do:
Find your antenna's true resonant frequency
Trim dipoles and verticals. Adjust your Yagi, quad, loop and other antennas
Change antenna spacing and height and watch SWR, resistance and reactance change instantly
Perfectly tune critical HF mobile antennas in seconds for super DX -- without subjecting your transceiver to high SWR
Check SWR outside the ham bands without violating FCC rules
Take the guesswork out of building and adjusting matching networks and baluns
Measure distance in feet to a short or open in faulty coax
Measure length of a roll of coax, coax loss, velocity factor, impedance
Measure inductance and capacitance. measure resonant frequency and approximate Q of traps, stubs, transmission lines, RF chokes, tuned circuits and baluns
Adjust your antenna tuner for a perfect 1:1 match without creating QRM
