Why not run two ground wires in parallel -- one twice as long as the

That will help on some frequencies but it is akin to trying to
erect a 1/2WL fan dipole for all frequencies - can't be done. Sooner
or later, you will run into a frequency where length #1 is N*1/4WL
and length #2 is (N+1)1/4WL. "It's not nice to fool Mother Nature."

OK then, I'll use 3 wires and take my chances! :-)

If you are on in a building that has prestressed concrete floors,
and coloums, try using the ReBar in the concrete as your RF Ground.
When I built my house on a concrete slab, before the pour I brought
up a steel strap bonded to the rebar and steel mesh in the radio room.
it was a very effective RF Ground clear down to 500Khz.
