That's what I mean by "at the bottom," at the bottom of the feed line rather
than at the top where the antenna is. The SWR is not improved, but the loss
is reduced.

I do not know what you mean by putting Balun at bottom? I place my balun
between the openline and the tuner. 130 ft attenna then the SWR is 1:1 on
all bands.
