The most intelligent, sensible and successful radio engineers make no
attempt to measure antenna radiating efficiency. It never occurs to them to
do so - they invariably calculate it.

It takes no longer than a couple of minutes on the back of a used envelope,
using a pocket calculator. It is more accurate and is absolutely certain to
be enormously less expensive.

But perhaps some old wife who cannot do simple arithmetic will find a fellow
creature somewhere in Google who is reported as having attempted to measure
it.

The real problem lies in the western world's educational system. Arithmetic
has been neglected for far too long. It will take two generations to return
to normal and dis-arm children who take loaded guns, even automatic weapons,
to school. Never mind about tower blocks. As a priority, teachers must be
protected from acts of terrorism.

But too late. Chinese and other Eastern countries' education, science,
engineering and technology will have already acheived supremacy.

But why make a battle out of it? I'm sure the peaceful, generous, Chinese
will be quite willing to share the products of their educational system.
