Your electronics and radio telecoms training seems to have missed out some very basic principles then it seems, like higher order propagation modes.

Aerial dipoles are not made thicker to increase bandwidth.

Exactly this. Thicker cables will carry higher frequencies and more power longer and further as long as those frequencies don't exceed the maximum cut-off frequency (i.e. bandwidth) of the cable .

Without girth, length would be impossible. But without length, the girth would be useless.
