My thinking is the current density is uniform in the outer surface of a round
tube falling according to skin depth at that frequency. At higher frequencies
there is no current on the inner surface so whether they touch when squashed is
immaterial, no current there anyway.
What is relevant is
This all depends on what is meant by antenna tuning.
When teaching newbies the wrong phrase can cause problems that are not seen
till later.
Antennas are tuned with wire cutters or a hacksaw so the feed impedance is the
desired value, ideally 50 ohm resistive or at least a match for the feeder
