Somewhere, G3TXQ stated that the values he calculated at
http://www.karinya.net/g3txq/chokes/ were subject to stray capacitance. It
doesn't take much to throw the values in his charts there way off.

That's another reason to not recommend chokes like that as a general
solution. Even for a single band antenna, a ferrite choke is cheap and more
predictable. :-)
