What is wrong with the coax radiating?
Art

Personally, my major complaint is in the "lack of control" over antenna
performance/operating characteristics.

For instance, with the feed-line allowed to radiate, movement/placement
of the coax tends to affect SWR, radiation pattern(s), etc.--sometimes
dramatically. This is very undesirable, at least to me, in a
mobile/field-day/camping/etc. antenna ...
