[Elecraft] open wire feeders

[Don Wilhelm]

Actually, that is a *brute* tuner, capable of mega kilowatts!  Something 
a bit scaled down is more practical IMHO.  BUT the design is exactly 
what I was referring to.

The design principle is the same, but I have always used dual section 
capacitors so the shaft is at RF Ground potential (no insulators 
required).  Number 12 or 14 wire in the coil should be all that is 
required for normal legal power levels.  WZ5Q would probably consider it 
"wimpy", but for practical purposes, it should be just fine.
