Since I originally posed this I have been making and trying all sorts of different ideas. I currently have an Arrow-style open stub j-pole on the rear deck painted to match, and a Fong DBJ-1 disguised as a plant on the front porch. But my favorite one so far is a Moxon style antenna I made with 1/4" wide adhesive copper tape around a piece of cardboard from the back of a note pad. This one sits in front of the window by my chair, and is pulling in repeaters that I couldn't get before. Thanks for all the ideas!
