MFJ-269 Antenna/SWR/RF Analyzer
It's ok, but has one known short coming (other than its known and accepted
general low/ medium accuracy). It appears to do worse at LOW freqs that the 259. Mine shows about 25% X for a purely resistive 4:1 load (either 200 or 12.5) in the 1-4 Mhz range. A post here not to long ago reported that the QST review showed the same thing. you can't expect lab accuracy for $300... 73, K9DCI "Roy Lewallen" wrote in message ... "Swiss Army knife" is a good metaphor. In your pocket, it's always available and handy for that simple job. It's got a saw good for fast, rough cutting, but no competition for a chain saw for speed or a scroll saw for precision. The file will cut metal, but it's not a Swiss file set or a wood rasp either. And so forth. Likewise the MFJ. I use is frequently for a quick measurement, and that's often good enough. But when I really need precision, out comes the GR bridge, network analyzer, and whatever other real tools are required. Ironically, the thing it does worst, in an urban setting at least, is actually measure antenna impedance. Like any broadband impedance meter, it's dismally bad at that particular job because RF from broadcast and other sources drives it bonkers. So by all means get one. You'll find you use it a lot. But don't be too quick to unload your other gear. Roy Lewallen, W7EL John Ferrell wrote: I am considering ordering the MFJ-269 HF/VHF/UHF Antenna/SWR/RF Analyzer. It sounds like a Swiss Army knife device and I should be able to send a lot of old equipment to Ebay. Does anyone have any comments to make on it? Good or bad? I have read the review in May 2005 QST and the manual available at their website. John Ferrell, W8CCW |
