Coil form material - Q-killer?
Original poster: "Gav D" <gdingley@xxxxxxxxx>
I have been reading the Medhurst paper from which the much used coil
self-capacity formula originates and noticed a formula for dielectric
loss. Using this formula and calculating skin-effects, I have found
that the PVC pipe often used for winding a secondary contributes more
to reducing Q-factor than the conductor itself; I am correct?
I would appreciate your comments,
