Radials do not affect the angle of radiation.

New antenna models arenas ideas for them are one thing, but new laws of
physics? It's great to experiment but you can only work around the
fundementals. Discovering new principals is always in play, but that is very
different from new configurations of metal. Even fractal antenna technology is

congrats for excellent job!!!
You arranged very nice setup even although the wx was against as same

Hope to see You on TB soon.

I think your take - knowing what the distribution is - is a worthy
consideration, Tod. Using a technique called Bernard's approximation and
given, oh, six to ten data points, and some graphing paper one could complete a

I currently use the spray on my patio, lawn and driveway as a ground system. It
works so well I took down my elevated radial system which made my XYL very
happy. Now I have a much more efficient antenna AND a much happier wife. I
have worked more DX on 160 this season than in all prior years
Amazing. Nano antennas aren't new but this guy presents them in an odd way, as
if they form a mystical improvement to normal antennas. His starting comments
are telling regarding the implied lossy nature of conventional cell phone
antennas as he cites the heat as proof as the lossiness. The
Hi,
Trying to get up on top band on my small lot (free of antenna
'covenants') has forced the issue for me. I will be putting up a stick
as tall as I can, with some sort of loading/matching, AND, as many
radials as I live long enough to put down. That for transmit. I will use
separate receive

Why struggle with or even bother putting down radials when you can use a

Jack,
As the all band demand would increase the load from a 100 users to
thousands, I guess it would be up to the system capacity and if the
antennas are capable of the bandwidth requirement at one given moment
without compromise. Maybe it would be done by subscriptions with on
line payment
Ag, Herb you have stumbled on to the idea we have joked
about here for some time. A pair of 8 element RX arrays for
diversity receive served up by subscription on the internet.
Located on top the double peaked 1200 foot hill 2 miles south
of the shack here of course. I can dream cant
That would be great Lee but one system won't be enough, you will need to put
up any number of systems so subscribers can be assured what is spotted can
be heard in their area...
Go for it...

Hi Jack,
Are you saying that the FCP works just as well as
an elevated or buried radial field???
I was under the impression that the FCP was just a way
to get on 160 when there wasn't room for a radial field...
Thanks for any feedback.

I just turned my webcam around and snapped a pix of the
proposed array location. How can I resist that low take
off angle on 160? Dreams, Ah.

Exactly. For those that missed it - there is more here:
I agree.
What I don't understand is how people
don't understand that UP means transmit
up in freq. Yes, some forget to switch

UP 3. Got it... but when the police
send your call on the DX Xmit freq then
tell you to transmit UP in the same

I DO welcome any discussion on exsting and new proposed antenna/ground systems.
However, discussions tend to be jammed by people throwing in basic theories,
papers, even laws of physics from those who seem to oppose a (valid) new idea

I remember when 160 meter and EME enthusiast Sam Harris (forgot his
call) used the Arecibo Space Telescope for moon bounce. His efforts
began a whole new resurgence of interest in this communications mode.
now even some DX-peditions are trying it.
That was the birth of EME, not a
