Ok - I had to go back to my M-o-M notes to find this little gem - for your
consideration.
y'all remember that I thought I had seen a M-o-M proof of a directional
antenna system with elevated radials get granted? Yes I said that a few days
back - pay attention.
Here's the antenna and ground system description:
TOWERS Electrical length: 75.9 degrees plus 10 degrees of guy wire top
loading.
3 - towers 51.8 meters above base (170') tower steel
GROUND SYSTEM:
Elevated counterpoise system for each tower consisting of 6 equally
spaced radials 62.4 meters in length, 6.1 meters above ground, unless
truncated by property boundary..
WGNY 1220 kHz, Newburg, NY Mr. Beverage filed the application.
Application file number: BMML-20090603AHD
You can see the whole application in the application correspondence links
(it was amended a couple of times)
This will head you in the right direction for those interested:

So there you have it - a directional antenna system with elevated radials,
top-loading and a M-o-M proof!
A perfect storm of dazzlement and amazing wonder.
I suspect that no questions were raised concerning the rms of the system as
this was a previously licensed facility that converted to a m-o-m proof.
The rms of the directional antenna system would only have been asked if it
hadn't been established previously with a traditional proof. I haven't
checked the full record about that, but that's what I think happened. AND as
I had no conflict (clients in conflict) with the application, well we simply
just made a note of it and filed it in the "well-this-is-interesting" file
and promptly forgot about it - sort of.
TZS (still grumpy).
