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.

Wayne, you're wasting your breath. You'll never get Gareth to see sense on
this. He's been banging this drum for years now.
