I have a Kenwood ts440s w auto antenna tuner. I am running a g5rv
antenna and the auto does not tune on all bands. I know I need an
external manual tuner, but do I get the one with the balun built in or
not. I have an airwound balun at the feedpoint for the coax from the
ladderline of the antenna? That is for current prevention on the
outer part of the cable as per manuf. instructions, dont think I
really need that though.
Thanks

I have a friend with a modern solid state rig with built-in auto AT, also,
and he cannot match all of his antennas on the appropriate bands, either.

I gave (he actually bought it from me) him one of my small manual ant
tuners and it matched up fine with negligible reflected power.

You may have to do the same thing, but you should read your manual about
how to disable the internal automatic antenna tuner.

I presently own an Elecraft 4:1 100 watt balun and I'm running a Van Gordon
All Bander antenna that is fed with 450 twinlead.

My Yaesu FT-890/AT's tuner can usually find a good match wherever I go. Now
and then I find a place where it won't match up, but the great majority of
times it matches perfectly.

My Icom IC-737's autotuner was almost as good at matching on my present
antenna as the Yaesu FT-890/AT.

I wish that an autotuner manufacturer would recognize the market for folks
using antennas fed with twinlead and offer us an autotuner designed to
operate accordingly. Were the price reasonable, I would be there buying like
stink on manure. A high power version would be attractive to me too.
