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

Compared to the MFJ 989C roller inductor tuner with the built-in 4:1 balun,
I have not been able to match the 989C's very wide tuning range with a
smaller 300 watt tuner running into a 4:1 balun. It is my suspicion that if
you need a long of "tuning swing", you'll likely not find it by running a
normal 50 ohm tuner into your 4:1 balun. It hasn't worked for me in the
past. Of course, I haven't tried every MFJ tuner that would meet the
criteria, much less all of the other brands of tuners.
