Seeking recommendation for antenna tunerSubmitted by George.Polich on Wed, 04/23/2008 - 1:02pm.I am researching antenna tuners. Will be my first one; so reqiuire something that will be versatile and adaptable to future radios (currently have an ICOM 7000). I am seeking comments on what others are using, if they serve them well, and why or why not. George |

MFJ 993B
I have been using the MFJ 993B auto tuner with my IC-718 for several years. Very reliable and the built in memory shortens the tuning time for oft used frequencies (e.g. PSK31).

My 2 cents worth
George: I just got an IC-7000 and a MFJ 929 tuner. It's a bit smaller than the 993, but has most of its features. The ICOM sits on it very nicely, since they are about the same size. I fabricated a connection cable to the ICOM and it autotunes with a push of the radio tuner button. I have an off-center-fed dipole (windom) antenna with a coax leadin, and this tuner works fine with it. I'm certainly no expert, but I thought I would pass this bit of experience on. Incidentally, the cables are very hard to find. I'll be glad to make one for you for a nominal fee.

Seeking recommendation for antenna tuner
George,
There are a number of very good tuners out there. I have at least three any of which should work for you. One is a manual tuner, but the others are autotuners that work well. The autotuners are the LDG AT-200pro amd the MFJ Intellituner, MFJ-993B. The manual tuner is the MFJ-969 roller inductor type. Any of these will work well in most circumstances. We can go over the issues at the next meeting.

tuners
George,
The answer as always is that "it depends".
Are you looking for an auto tuner, a manual tuner,
one for portable ops, one strictly for wire or vertical
antennas, a qrp tuner, mobile setup, etc....
I'll assume that you are looking for a base station tuner,
100 (or more watts) and want an auto tuner. I did a buncha
research on these types before settling on the MFJ-993B.
I am not a big MFJ fan; however, on the rare occasions when
they get one right, it's a good product. The 993B (995 for
higher power) is one they got right. In all honesty, it looks
like one where they had someone else do the design.
If you're looking for a manual tuner (again, I'll assume that
you're not looking for QRP), it's hard to beat some of the old
roller inductor tuners that come up on e-bay all the time. Specifically,
the Heathkit 2040 or 2060. Amp supply made one that was nothing but
a completed Heathkit.
Unless you have a burning desire to spend time twiddling the dials
on a tuner, the auto-tuners are hard to beat.
