[TowerTalk] Feedline (choke) question

[John Keating]

On a related topic, I'm getting ready to put a Mosely PRO67-C-3 on a 
tower. The instructions call for a coax choke, 10 turns of RG213 in a 
10" diameter, taped to the boom, and within 3-6" of the choke, split the 
coax and wire directly to the phasing lines on the two driven elements. 
When I asked them if a conventional toroidal common mode choke would 
work they said it would be likely to affect the tuning of the antenna. I 
wondered if anyone can comment.
