Sound's great and will certainly have to give it a go after my loop is upon it's final mounting. What is your QTH area like Bear? Is it flat or are you in a valley or hollow or are you on top of a

Hi Bear, Just joined the group and checked out your early results of the new geomantic Spiral antenna, very interesting stuff. When you are ready you will have to give a photo and more detailed

Locked The Geomantic Spiral
Gents... I have built my first geomantic (ground-coupled) antenna which I am calling the Geomantic Spiral. It's nothing more than 30' of RG58 coax rolled into a tight, flat spiral and placed on the

Since the subject of Geomantic Antennae can get rather far afield and lead into some other rather peculiar areas (dowsing, radionics, Ley lines, etc) I have created a new group

Locked Geomantic Antennae
No... they ain't loops but they do offer some interesting potential that seems worthy of exploration. Especially for ground dwelling folk like me that have limited area for antenna farming. They are

Hello All: I, too, have been playing around with this idea. Some time ago, I bought a couple of tin (yes, real tin) plates at a hobby shop. They were about 4X6 inches in size, and I soldered a wire

Howdy, Gregg, Welcome to the group and thanks for the links. The design of your loop's support structure is especially interesting to me. I've been kicking this around for a while without coming up

Hi All! New to the group, but not to radio. When I was a kid (very long ago), we used to make our own variable capacitors. Basically, we'd take a square of wood, varnish it well, and mount a square
