To All,
Tony Wells, G7IGG <[EMAIL PROTECTED]> and I are testing an EH
antenna vs a normal 1/4 wave dipole and we need some signal reports.
The test is using my K2 and Tony's Beacon Monster software. I am operating
a manually controlled beacon on 14.102 MHz. The software times the beacon
and commands the K2 to send a brief message on one antenna then switches
antennas and sends on the other. See http://www.tinyurl.com/6oh59 for
details of the message and the status of beacon.
This is an example of what you can do with the K2.
Please send signal reports to me. The best way to measure the signal
report is to use Spectrogram, MixW or Spectran to measure the signal
strength. If you can record a .wav file with the AGC off, please send it
and I can analyze it with Spectrogram.
Locally and in US, preliminary results indicate the 1/4 wave dipole is 3 to
6 dB stronger than that from the EH antenna. I have some reports from
European stations that the EH is 3 to 6 dB stronger, but I have a very
small sample; that's why I need more reports. The old adage that a
vertical antenna radiates equally poorly in all directions may not be
true. These antenna may have some directivity.
