The tall solenoid coil has a winding length of 48.125" on 3.5" OD PVC pipe and wound with 21 gage wire. A jacket of 4.5" OD PVC pipe was then placed over the windings and sealed at both ends. The space between the jacket and the windings was then filled with transformer oil. This jacketed coil has absolutely no corona. An interesting side effect is that a very strong static charge develops on the outside of the jacketed coil for the full length of the PVC.
