What I want to do is to use the 8-element form, and I want it to work whether
the pole is inside the box or not.

The example I've given above can be done other ways. Sure. But *it ought to
work as I've given it*. It doesn't. Why not?

Does anyone out there have experience of using the 8-element form,
preferrably with a /ster projection?
