Default The inefficiency of short antennae compared to long antennae, as previously discussed.

This is one of a series of lectures by a prof at Texas Uni.


In fact, if you go right back to the home page of
http://farside.ph.utexas.edu/teaching,
this leads to a most excellent revision of the necessary EM theories, and,
briefly
glancing thereto, the post grad stuff even exceeds my current interest and
knowledge.


I'm fairly sure now that this area is where I came across the governing
formula that I
alluded to recently in this NG when doing my own revision previously in
2005, although
the URLs and lecture node numbers have changed since then.


When I get time, I'll browse through the links.

However, back to your original assertion that your theory has short antennas
as being inefficient compared with longer antennas (I'm assuming you are
talking half wave dipoles and such).

If 10 watts is delivered to a short antenna, where does it go if it is not
radiated just as well as 10 watts delivered to a long antenna?

How are you going to deliver that 10 watts? By feeding with 100 Watts?

Oops! Is that part of the problem? You never said matching was involved.
Please get your story straight.

Tell us your requirements. Using real wire? What diameter? What
material? What length? Is feeding the antenna part of the problem?

What the hell are you seeking?

Untrue.

The confrontation is sought only by those who seek to respond
in a tendentious and abusive manner, such as John S and rickman
above.

In what way have I been abusive, Gareth? As for tendentious, it you who
have done so with most all of your original posts. It seems to me that
you are a lost and lonely soul and are seeking some attention. If you
wish to discuss technicalities of ham radio, I'm all for it. Can we
please be gentlemen about it? If not, I will never respond to you again.

He wants a row, as always. Why else is he hurling abuse and ignoring
helpful posts?

That is what he has always done.

You are the one who is hurling abuse. For example, all of your posts to
this thread so far are personal attacks on me.

Attention.

He's a very sad, demented attention-seeking troll, as evidenced by the
Google archive of his posts dating back to 1997. What's striking about
them is that they haven't changed much in that time.
