Default Need help... End-fed, long wire or ????

Hi Denny, thanks again for the help... I guess I should expand a bit.. I'm
not just thinking of a manual tuner, but also an auto tuner, like used
Triton, SGC or Icom marine/military type,


Well, with the remote autotuner you will have less RF in the shack...
But even then I would hang ground radials off the tuner case to keep
it at lower voltage potentials...
Since you are willing to spring for an SGC, etc. given your
description of your site I would think about an off center fed wire
antenna... Run your longwire through the trees... Roughly an 1/8 wave
lowest band back from one end of the antenna drop a vertical wire
to the ground and use the tuner to feed the end of the drop wire... A
ground stake and some radials and you are likely to be in business...
You can fool with snipping a bit off the long end of the wire if one
of the bands gives the tuner a hard time... This should play...

Now, ALL the tuners you mentioned and I know of are single ended, i.e.
are not truely balanced for balanced feed line and putting a "balun"
on the end of the ladder line does not make it a balanced tuner...

Now, I use open wire feed for the majority of my antennas, but I build
my own balanced tuners and open wire...

cheers ... denny
