Jim,

Speaking of widebands.. what about recommendations for chokes to use 
with an autotuner at the feedpoint/base. That *is* a broadband 
application.  My practical experience has been that you need to choke 
both the feedline AND the power/control lines to the tuner (not 
together.. one choke for coax, one for power).  And, probably, choke it 
at both ends.
