Looking at Comet caa-500 to buy. what do you use? why? reviews?

I've always used a MFJ-259xx series analyzer. All I was interested in (at the time) was setting up antenna's, and once that was done I would usually sell it. However, I've owned the Comet Caa-500 for almost a year and it's very nice as well. It covers up to 500 MHz. Depending on which version of 259 you're looking at, it's coverage will vary.

I'll admit that I was hasty in my decision to buy the Comet, and had I thought about it longer I may have bought either a used MFJ-259, or the RigExpert model that let's you store results on your computer.

I used the Comet a couple times to setup mobile antennas, but I use it daily to tune my Magnetic loop (and that makes for a very expensive MLA SWR readout)

If you're in a hurry I guess *NEW* is the fastest option, however I've seen various used MFJ-259's (over the past 10 months) go for $125-$200, and the Comet for about $275. Whichever one you pick will probably do exactly what you want it to. ;)

I don't know if you saw it, but there's another post that has some legs on it about what antenna analyzer to buy -

Look into Rig Expert brand. Well made, easy & intuitive to use. Better IMO than any MFJ, costs less than a Comet, comes with a protective weather case for use outdoor. Will give measurement length of coax, length, Smith chart & way more. Nice large color display that is easy to see even in daylight.

MFJ 259B I've had about 20 years, and for VHF/UHF (UHF ham and GMRS, primarily) a RigExpert AA-650 Zoom. Spend more on antennas, coax, connectors, adapters, ferrites, antenna tuners, and antenna analyzers than on the radios. Thought I had a radio hobby, turns out I have an antenna hobby.

I have a MFJ259. It's an early version, no letter designation, but it does what I need it to do. I don't use it too much, but it's nice to be able to test and adjust SWR without having to attach a radio and keying up. It gives a nice quick test. Of course it does a lot more, but I haven't found myself using it for much other than playing around finding coax length without measuring...another toy to play with.

I checked a neighbors truck antenna as the radio he had blew the finals. It gave me a quick test to see if it had a bad SWR or open or whatever, without having to attach a radio and key up possibly harming the radio again. Turned out it was OK.

MFJ products have a mixed bag of reviews, but I think in this instance, at least for my purposes, the MFJ works just fine.
