PT0S describes a "garden beam" antenna here:

http://pt0s.com/equipment.html

A Google search gives a site marked for "suspicious activity."

Does anyone know what this antenna is and what its performance characteristics are?

Thanks and 73,

I've seen other references to that antenna.

There is a photo on the link (if you can see it.)  Basically it is a vertically
polarized yagi with horizontal radials for the bottom half, sort of like the
Gizmotchy CB beams.  Looks like the 20m elements might be folded to
reduce the physical size.  Using horizontal radials in place of the bottom
half of each element allows it to be mounted on a short mast with less
ground interaction - ideal for use on a small rock in the middle of the ocean.

That antenna might work well but I am pretty sure I would not want that sitting in my back yard  Wink

It is very much along the lines of what Moxon was talking about in his book, Hf antennas for all locations.   P165 has a diagram of a Monopole with a folded loaded counterpoise.

The GB site, seems to be inaccessible, my browser wont let me get near it.

The site says the antenna "Gives performance without the need for a tower"

I say it better give performance for as big and ugly as it is.
Definately looks the part of a HAM device.
