A big thank you to Frank, VO1HP, St. Johns, Newfoundland, whose
successful version of the L + FCP + short tower is the genesis for
this method.
FCP refers to the 5/16 wave single wire folded counterpoise for low
bands, described at http://www.w0uce.net/K2AVantennas.html At some
point an illustrat

It seems to be back. Or perhaps it's another one. On 1813 now.

Perhaps a better definition of far field is the point of increasing
distance where the shape of a pattern calculated by a near field process
quits changing at angles and azimuths of concern.
Let's test this idea using the NEC4 near field table generator. We will
not change processes, using the n
Hi everybody, I would like to try K9AY antenna for this CQWW mainly for 160 but
after the contest I hope it to be usefull for 160 and 80.
Q1: would it be possible to use a tree as a central support without affecting
its performance? or would it be better to hang a rope between 2 trees and hang
Since ferrites are discussed so often on the forum, I thought this article
in High Frequency Electronics (edited by K9AY!) might be interesting:

Lots of good information on ferrite "hows" and "whys."

According to antenna engineering textbooks (Kraus, Balanis. Johnson &
Jasik etc), the free space, far-field radiation pattern is not a function
of the distance from the radiator, as it is in the near field. The
near-field/far-field boundary conventionally is defined as equal to
2L^2/lambda, wh

Would like to hear from you if you can shed some light on this.
Near San Francisco, I see JT65 activity fairly often from VK and the
east coast, and on the very best nights the east coast guys can work the
VKs. It's a fairly narrow
