- Yes, later SB220 had a higher voltage breakdown (wider space, more plates) capacitor that was longer. It generally came with a special end bracket for mounting the 10 meter coil. 73, ... Joe, W4TV _

- Martin, I had to do some review but now that I looked at some SB-220 pictures, it seems that what they did was use a threaded stand off between the tuning capacitor end of the 10 meter coil and the l
