On 2/05/2008 2:30 AM, the old scribe known as Colin McDonald was able to
impart this pearl of wisdom:
> hey Shaun:
> I did research these last year.
> The E H antenna looks like a fairly interesting idea. I have no doubt that
> it does perform as stated.
> I think it would be fairly easy for a blind person who is mechanically and
> electronically enclined to build.
> Of course the problem is, as with most antenna designs online, that much of
> the building steps are diagrams and pictures and not written out in plain
> language.
>
> The theory behind the E H antenna design is still a bit hard for me to
> understand, but even so, I do respect the claims of those who have used it
> and who designed it. Just because one doesn't understand the theory,
> doesn't mean that the thing doesn't work.
>
> One must also realize that this antenna is not some miricle antenna that
> will out perform a mono-band dipole or larger vertical.
> It will perform up to nearly the same performance as a dipole, and it is
> much more efficient then your typical vertical antenna.
> that is to say, that it transfers a much larger portion of the RF into the
> air instead of into the ground as many vertical designs tend to do.
> It is also a ground-plain free design and can be used either mobile or as a
> stationary antenna.
>
> For situations that require a suttle antenna, or stelth antenna, these E H
> antennas are a good idea since a 20 meter version is only about 2 feet tall.
> If you can find someone who would be willing to decode the diagrams and pics
> and write out a comprehensive text version of how to build the thing with
> measurements and formulas, I for one would be very appreciative since I've
> wanted to try building one of these for a while.
