Hi,

Interesting you brought this up. I just bought 100 ft of primary tubing at Home
Base (btw, going out of business and 50 to 70% off) to wind conical
primary's and
test against calculated inductances via Fr measurements. Conical primary's are
cone's (I know, duh). The only problem with a conical primary is that the outer
windings are typically higher up on the secondary and therefore have greater
potential to take a strike from the secondary streamers. What if it is wound
downward? The secondary coupling would then need to be checked via current
measurement to see how far down the secondary should actually be to achieve
similar coupling on an upright cone. This is part of my current experiments
coming
soon.
