I had a dome idea.

....again. Happens every once in a while.



I had just added two antennae to the top to call out the edge vertex orientation, when I lost control of the software. ....again. So I grabbed a screenshot, and added a high-pass filter in GIMP to bump the contrast. No HDRI lighting and verdant lanscaping yet.

But I can use this to point out some advantages of the edge vertex orientation, which is free to everyone, but sadly un-used.

One advantage is bilateral symmetry. This means there is a front and back and two sides. This answers the 'how do you put it on a square lot' question.

Every frequency has an equator. With vertex zenith only even frequencies offer a natural equator. However, if you go beyond a hemisphere, it presses inward on any stem wall (or multi-stories) so no compression ring is required.

Also, consider the eight triangles below either of the antennae. Those could be projected into a gable end. The result would be an inflato-A-frame.
