YES, if it's inserted at the base of each vertical element, as it should 
be, it becomes part of the phasing line. And be sure to consider the VF 
of the feedline you're using for both the choke and the phasing line. 
Also, the choke should be 75 ohm coax; there are photos and text about 
suitable coax in my Cookbook. k9yc.com/publish.htm
