Topband: End Fed Twin Lead Marconi Antenna

[Garry]

I would like to thank all who responded to my post. Your comments are 
most helpful. I have been studying ON4UN's Low-Band DXing book and in 
particular, the section on vertical antennas, ground planes with 
elevated radials. In most cases it seems the more radials the better 
with even numbers of radials illustrated. I wonder why the antennas at 
WWV are using ground planes with 9 radials? Nine just seems like an odd 
number and I wondered if there was a reason for this number as I don't 
see any explanation on their website.

Thanks again,
Garry - WR4R
