The capacitors aren't really needed, if you just short the far end  it works
OK - a system which I work here to a ground mat, and use a Marconi antenna
on 160M.

That should work, but I'd suggest an old trick we use to use.  Use coax 
cable for your ground wire, that is the center conductor.  Bypass the 
center to the shield on each end with a .001 cap.  This shields the 
ground and prevents it from acting like an antenna.
