A few years ago I wound a bunch of coax choke baluns and measured their
effectiveness with an HP vector impedance meter. I wrote up the results,
and that paper is on the web at
http://www.berkshire.net/~robbins/technote/airbalun.html
Coax choke baluns do indeed work very well. You can look at the numbers
yourself and draw your own conclusions.
