Dr Mal --

Do you use anything as a sort of line isolation transformer in your dipole
design?  Or... do you just connect the coax to a simple center conductor
and run with it?  Some advocate a several turn coil to minimize the chance
of RF on the coax shield.  What is YOUR take on this in your design 
paradigm?
