Dwight,
The ends of the 1/2 wave horizontal bipolar must be kept as far from anything 
as you
can get them. Air is the best insulator. The ends of the coil are sparking to 
eachother and the problem is to shape the e-field so as to direct that spark 
out and away from the ends of the coil. Arching the secondary like a slinky 
to put both ends of the coil against a surface would be the same as placing a 
vertical 1/4 wave coil upside down on concrete.

My 20-inch bipolar produced a full 20 inch spark. My error was in scaling up 
too large to
a 48 inch coil so I simply ran out of space to insulate the coil. If I repeat 
the experiment
it will be to reconfigure a 24-inch coil in another attempt to get a spark 
larger than the physical length of the coil.

Hope that answers your questions.

Happy day,
