A Good Basic SWR Analyzer

Got one used on eBay for new interest in antenna tuning. My tests on a 40M dipole with balanced feed fell off the C scale where 7MHz is on the low end. Seems sensitivity lessens greately at end points. However, resigned to cut ant. to 66.3 feet, set the analyzer freq by coupling to receiver, then couple into a Johnson Match Box where tuning produced near perfect SWR reading on the MFJ-207. Not sure if the meter drop off is proper, but I got assurance of a good match with mt method.

Great tool

MFJ-207 analyzer is basic but efficient tool for antenna tuning and development. Analog scale is rather coarse but once set, frequency is quite stable. Good investment if bought used. For me it's a keeper.

Analog scale

I agree with last review, except add that for checking antennas with a narrow bandwidth, i.e. 20kc on 160, or say 40kc on 75/80m, a digital readout like the MFJ-259/269 would be better, more accurate, $$$ss well spent. The -207 has an analog dial/scale. I bought the -207 mainly for mobile use in getting hamsticks, etc. tuned, and for base use with a multi band vertical, AV-620. For these two applications, it is easily adequate, and has a fairly durable enclosure and design. As MFJ consistently makes excellent antenna analyzers, the inferior workmanship of some of their other products is a mystery.

Here is a cheap way to play with your antenna systems. The tuning dial is crude so you need your receiver to locate the exact frequency. Once accomplished, you can resonate any antenna very quickly. A real asset to any ham who likes to buld antennas.

This is my second MFJ-207. Some one borrowed the first and I had to buy another. I liked the smaller size for disaster relief work. The first time I used it was on a mobile radio setup. The guys had been trying to tune a whip antenna for some time. I asked to try my MFJ-207; five minutes later we had completed the tuning. I have a MFJ-259 and used the 207 in the same manner. However, the 207's I have had, had a quirk. The tuning knob and the dial in no way come close to reading the frequencies correctly. So one must set the radio to the freq. then scan the band with the analyzer tuning knob until you hear the analyzer signal on the radio and note the dial setting for that band on the analyzer. Now you can tune the tuner. To find the resonance of the antenna look for the dip in SWR, and tune the radio until you hear the 207's signal; that is the resonant point. The first 207, needed only to relocate the tuning knob to set the pointer nearer to the correct spot on the dial; all the readings were then closer. The second 207 was off on all the bands and relocating would not take care of the dial problem. So I just learned the approximate locations on the dial and let it go. Works fine if the dial quirk doesn't bother you. Also on both 207's the meter needle slammed into the stop on power up. I found the recessed pot (lower left) and reset to peak on the red scale. Barring the quirks; I found myself favoring the use of the 207 as it is accurate, quick and the battery seems to last forever; the smaller size is a plus also. I carry it to disasters as someone always needs help in tuning up.
