Capture area has nothing to do with physical size.
That is folklore.
Capture area relates only to gain and frequency, not antenna size.
Gain is not related through any rule to physical size. That's just an
excuse used to make some antennas be magic, when facts prove
otherwise.
It's not how large you make it, it's how you make it large.
