Homer, if we accepted your capture area idea as one of the primary conditions for improving gain, then we would probably only see very long thin wire antennas in use. Capture area and bandwidth are compromizes, not antenna characteristics perse.
Some folks around do run long thin antennas for similar reasons, so you may be in good company with the idea.
However, consider the possible contridiction with guys trying to minize common mode currents from working in excess on their antenna feed line. IMO, they are in affect minizing the capture area if they are successful.
Only with my modeling do I think I'm able to see sometimes where such CMC's issues can be benificial in how well the antenna works, and in other cases the effects are more detrimental. So, we can take our pick.
Some folks, like the guys at Solarcon and others maybe, will suggest to you that having the feed line radiating right along with the antenna is a good thing however.
Looks like nobody is willing to speculate on the result possibilities I asked about. What does that tell us?
