Jul 11, 2013 · The MFJ-259B and similar instruments are very useful for trimming or adjusting antennas to resonance. The MFJ-259B is great for Amateur Radio purposes, but it doesn't go low enough to cover the Medium Wave frequencies (like the AM Broadcast band) or even lower for LOWFER people.

The first method involves placing a 50 ohm resistor in series with the MFJ-259 "ANTENNA"... Page 16: Testing Rf Chokes This magnetically couples the MFJ-259 to the resonant circuit. The frequency of the MFJ-259 is adjusted for a dip on the "SWR" meter. All information, images, and documents on this website are the sole property of MFJ Enterprises, Inc.

MFJ 259B HF/VHF SWR analyzers are compact, battery-powered RF impedance analyzers. They combine four basic circuits; a 1.8-170 MHz variable frequency oscillator, a frequency counter, a 50 ohm RF bridge, and an 8-bit micro-controller. The analyzers make a wide variety of useful antenna or impedance measurements, including coaxial cable loss and distance to an open or short. Primarily designed ...

I also bought an MFJ-259, primarily because it will work on VHF, but have not powered it up yet - it is a backup. The Rig Expert is way more user friendly and ergonomic than the MFJ-259 and only requires 2 AA batteries compared to 10 on the MFJ-259. Going over some previous post I see that a lot of people have read my little summary of the MFJ 259b. This is what I originally said: "The MJF 259b has finally arrived, it’s a fiddle though, you would have thought you’d get the power supply with it, but no, that has to be ordered separately, typical!

This is arguably the most popular antenna analyzer on the market. MFJ has several other models with different feature sets. YouKits FG-01 – $250. This is a very cute, little analyzer with a small graphical display. It seems kind of expensive, but the graphical display might be worth it. Comet CAA500 – $450.
