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

If you're bringing coax into the shack then there's no need for a
balun built into the external tuner -- but a bigger tuner may work
better than a smaller one, by virtue of its wider tuning range.

The g5rv works best on 80, 40, 20 and 12 meters, so what your internal
tuner is already doing may be about what you should expect, anyway.
