Default language and antenna gain

But that does not mean that it has all of the electrical
characteristics of a linear conductor that is inherently resonant,
without the need for inductive loading.


Yes, replying to Richard but also to Roy and Dave.. maybe i can't explain
very well, but the sense of my latest question is this:

if a half wave end-fed *monopole* antenna have the following primary
characteristics (if IIRC):

- High Z at the feedpoint (voltage maximum and current node);
- very small counterpoise lenght compared to the resonant wavelenght of the
antenna (typical 0.1-0.2 lambda)

can i mantain the same characteristics shortening the antenna in any way ??

Thanks for read and explain to those who want clarify my doubts.

Google EZNEC and find Roy's site.
Download & install the demo version- it is free!
Go through some of the simple examples like dipoles, 1/4 verticals
etc.
Bring your questions back to this group and we will all benefit.

Antennas are pleasantly addictive!
I consider myself a perpetual student...
