Auto-Tuners with balanced antenna?
 

Any recommendations for an automatic tuner that will work well with
balanced antennas fed with 600 ohm ladder line?

Specifically, I have in mind a 160M dipole fed with ladder line.

Well, I've not tried THAT, specifically, but my MFJ939B will load a 50foot
piece of what looks like 200 or 150 ohm twinlead with half of one side
stripped away just fine, if I connect up the internal balun. And I mean
LOAD it--on any frequency from 1.8 to 30mhz.

I've also loaded small loops with it well off their resonant points and use
it all the time to lead hamstick whips well off their resonant points.

I don't think you'd have any real trouble as long as the 600 ohm line ran
straight away from the antenna, at least in the near field.

I use the LDG z100 with and external Balun Works well for me.

I run a SGC ATU to my Dipole with ladder line with no problems

Isn't that contrary to SGC's recommendations?

Only if you believe that SGC, has a CLUE about how their autotuner
works, and the design of the firmware that runs it.............

Ed,

Take a look at http://www.hamware.de/index.html Just got back from
Dayton, and the ones on display looked solidly built, though that is
no indication of how well they actually work. Eham has some positive
reviews of an earlier model. No personal experience.

I am just about to install a hamware AT-502 in my back garden to tune
a 67ft doublet fed with ladder line. On 1.8MHz (and sometimes on 3.5 &
7MHz) I'll be using the ASU-502 accessory switch, strapping the
feeders together and tuning it as a T against a crappy ground .
I'll let youse all know how it works out.
