How big do you want it? Tell me and I will MAKE you a big coil. Three
inches is a pretty good size, but can go bigger.


I have a different question than the original poster had, for you. In
making those coils, What do you use up the center of the coil to both
insulate, and connect the lower mast and the upper whip? Assuming
standard 3/8" 24 threaded connectors.....
