Hi all,
for any doubt you have please ask to Mr. Graham.
He was hired as an indipendent consultant and he's responsible for the
data.He has more than 30 years of experience.
I think to know very well the antenna, but I invite you to refer to him.
73's and best regards

Hello,

After sometime ,I am here again to inform all the Om community interested
about the last news on the EH antenna.
The antenna was tested, following the FCC rules ,by Stu Graham a important
broadcasting engineer.
For any news and to read any data on it (including the complete report
from
the consultant) please go he
http://www.eh-antenna.com/AM_Broadcast.htm

Please read all the docs related.

Three years ago I put on this forum a special announce about this
important
discovery.
Now we can publish all the evidences we were right.
There is no doubt, the so called "EH mode " is real and alive.
During the test the antenna was installed at about 1/10 of a wavelenght .
On this position alomst equalled (only -0.4 db) a perfect 1/4 standard
tower
with 120 radials.
The real important feature is we can trade height for gain.
When the antenna is installed at 1/4 wav. it shows a 2.5 db of gain ( yes
,
GAIN for a ground wave over a standard tower)

very high efficiency
very large bandwidth
very compact size

For the ham applications a new era is approaching. Antennas on 40, 80 or
160
metres are very small on size, showing the same or better efficiency over
a
standard full size vertical dipole.

I wanted just share this great news with all interested people.
My best 73's
