Don't they tend to be directional off the pointy end?

No. Electrical waves are right angles to the conductor, often shaped
like a doughnut. But it doesn't matter in the near-field, as the signal will be
everywhere.


"LONG" wires, multiple wavelength antennas, exhibit gain in the
direction of the wire - bidirectional if not terminated, unidirectional
if terminated at the non-fed end.

You are thinking of the classic basic dipole.

That's exactly correct...I was going to reply to that but thought
someone could likely describe it better...you just did Dave.
