Default Why is it?

For example, it is well established in the technical literature at
degree level and
above, that short antennae are poor radiators,



Only if you progress so far above degree level as to reach cloud cuckoo land.




which is modelled by the distribution
of energy being attributed to an apparent radiation resistance of an
extremely low value,


That clause is totally devoid of meaning.




although in actuality there is no resistance in the sense of Ohm's Law!




AFAIK radiation resistance is totally obedient to Ohm's law. The fact
that radiation resistance is not fabricated from a piece of
poorly-conducting physical material does not make it any less a
resistance with all the necessary properties to meet the definition of
resistance, at a given frequency.


Sorry to join in, but I do think the total number of people agreeing
this is incorrect is important for readers trying to assess who is
right.
