You go into details.

Yes, I do go into the details.

In the Gas Analogy the monopole antena is exactly like the Kundt's tube.

Analogy is a false arguement.

Heaviside did the Hydraulic Analogy. All is exactly the same like in the
fluids mechanics.
Next the electrons were discovered. Automatically Heaviside is a history
and the Gas Analogy is in power.


In the car-seen-at-a-distance analogy,
this proves that only midgets or pygmies drive cars because we are too
big to fit into such small things seen in the distance.

But you, radio people, are very close to waves and should be easy for you
to work out the answer for the Question:
Which Analogy is right?

I will be absent till Monday evening.

neither analogy is 'right'. they are useful in limited circumstances to
demonstrate some basic pressure wave physics to young students. but neither
one properly reproduces electromagnetic waves.
