When I first got into ham radio, I bought my rig and the tuner together for $450. Now, I'm glad I bought it. I was 16 and thus still home-bound when I started, and space for any kind of antenna setup was limited. I put up a dipole that was cut for 80 meters, but I didn't have enough room to stretch it to a full 180 degrees. Best I could do was about 80 degrees. I figure this probably messed with the impedance, but this tuner tuned it on all bands from 80 all the way down to 10 with no problems whatsoever. I typically got my SWR down to about 1.5:1 or less. I don't run legal limit power (amps are way too expensive for my current wallet size), but I am at least glad to have this for when that time comes. If you can find one used somewhere, you won't be disappointed.

Workhorse Tuner

I purchased my first MT-2000A back in the 70s, and am using that tuner still! I now have a total of five of them, the last four purchased in the past year on eBay at reasonable prices!
The only weakness I know about this tuner is the tendancy for one end of the fixed inductor stock to suffer from melted insulation spacers. This happens when used with hign power on 10 meters, and each and every MT-2000A I've opened up has this problem! I don't use tuners on 10 meters now, so it's not a problem for me.
I use the tuners to tweak my wire antennas from CW up into the phone bands for phone contests, and these simple, rugged tuners are perfect for the purpose with the Alpha amps providing legal limit power. The MT-3000A tuner is essentially the same inside, but with ugly outsides and too many meters and switches for anyone to want!

The Dentron MT-2000a is a tuner rated a 3KW, but we all know that hams don't run 3kw, :)
This tuner has been out of production for many years but a used one can probably be found at a hamfest for 100-150 dollars. Not a bad price compared to today's tuners- check prices in QST.
The MT-2000a is a basic tuner, nothing fancy. It has a tuner/bypass switch (obvious use) and a lightening protect/tune switch, which simply routes to ground.
To obtain lowest SWR, you first adjust a switch labeled with the letters A thru L, until you hear the loudest noise on the particular frequency you are on. Then alternately adjust the 2 large knobs which adjust the large air capacitors until lowest SWR is obtained. I have been able to obtain low SWR on any band or antenna that I was using.
This is a plain tuner, no lights, no meters, etc..
It is rugged and easily handles the legal limit that I can use. If you need a legal limit tuner (or a bit more, hi) you can get this one at a hamfest for good price.
