A year a two ago I bought the materials to build a turnstile moxon pair as described by L.B. Cebik, W4RNL, in QST. I never got around building it, but it seems to me that they could be interesting too for an attic mounted alternative.

If anyone has experience with these, I'd love to hear about it.
