Me too. Well, let me rephrase... I have had the kit ($220) for about
8 months and have yet to start on it

First I figured I needed a better, smaller soldering iron. $100.

Then I got that and realized I can't see the parts. Got a 10X
Optivisor. $35.

Depth of field is really marginal. Got a lighted magnifier. $50.

Ready to go... oops no anti-static mat and right in the middle of
building bathroom vanity cabinet. Figured I could save money by DIY.

New Delta Unisaw. $1500. Dovetail jig. $400. Better lighting in
garage $400. Hardwood $400. Misc router bits, finishing materials,
spray gun, screws, door and drawer hardware and my labor at $0.05/
hour... don't ask.

Other than that, I use a Boonton 250 or an HP 8405 for impedance
measurements.

Hi Darrell,

I have used the Autek VA1 and the MFJ 259B here in 9V for about a year.
Must have gotten a good Autek as it has performed well. All of the MFJ
series I have used in the past and they will do the job but as has been
said, high RF enviornments render it useless.

The MFJ that goes to UHF we used on a field day trip to a remote island just
off 9V and it also did a good job. YMMV but the VA1 goes into a pocket for
a tower climb, is a bit fiddley, but I find I use it more than the MFJ.

I use the MFJ - because I could afford it at the time.
....and this analyzer post gives me an idea about the Stainless-steel wire
thread - hmmm

Group..I've just discovered this group (what took me so long?) and am
impressed with the knowledge here. I am shopping for an antenna
analyzer and am stymied by the choices (or lack thereof). In all of
hamdom (sub $600), I only find MFJ, Autek, AEA wireless, and Kuranishi
to choose from. I've checked eham reviews and found that the AEA VIA
(not Bravo) rates highest...and most expensive. Probably worth it.
Unfortunately, it's only good to 54Mhz, and I'd need up to 450Mhz. I
know this is impossible, and would be willing to go with separate
units (Autek), but they have awful reviews quality.

My question: What are you guys using for HF measurements? What about
V/UHF measurements? Do you recommend any particular model? How about
used HP gear from ebay (yes, I know the risks). V/UHF is my priority
since I'm building some copper loops for 6 and 2. What say you sage
antenna gurus?
