Topband: shunt fed tower - question?

[Bill Tippett]

KV4FZ:

 >Just read the post by W4ZV that he plans to use a 2 conductor shunt feed to
increase B/W.  I wonder if two conductors will obtain the "shielded from the
outside world" effect referred to above? Does it make any difference?

         Changed my mind since it's not clear to me it would
help much.  35 kHz 2:1 BW is fine for my normal use.  Would
go to a motorized shunt capacitor if I needed more BW.
