There has previously on the newsgroup been a claim that shortness makes
inefficiency.
To that I say that if for example, 100 watts is fed to a resonant HF
dipole, and 100 watts is fed to a 1 foot long dipole, both radiate 100
watts.
Different patterns, but the power radiated is the same, if you manage to
successfully get the power to the antenna.

The ratio of radiation resistance to ohmic resistance will give the lie to
your claim.

In my claim, equal power arrives at the long or short antenna AFTER the
ohmic resistances have already occurred.

Doesn't matter if you need 2000 watts to deliver 100 watts to the short
antenna.

My understanding is that you claim the short antenna is inefficient only
because it is short.
