Would winding the coax choke balun around the 
boom be okay?  Another question, would winding 
the coax choke balun on a 4" PVC pipe and then 
suspending the choke below the boom parallel with 
the boom be okay?  Both situations would make 
convenient the connection to the coax feed line 
and to the feed point on the ant.

Getting ready to do maintenance on the two F12 
EF240Xs on the tower.  Plan is to replace the F12 
baluns with either coax choke baluns or W1JR 
baluns.  Like Bill, W6WRT, 1500 W RTTY is used on the ant.
