Mike and TT's:
The ARRL Handbook has a table of this info.
No, research on the way to wind these coils has shown that it's better to wind
them randomly, not side-by-side. That provides trhe max Q. This is for
monobanders. For tribanders, side-by-side winding is ok.
Yes, monoband coils are different from tribanders.
