I've been thinking about a 70cm antenna made by using copper tape on a
window. It seems that I can get a 50 ohm match by drooping the two
radials about 38 degrees below horizontal. Of course, I don't know how
to include the effects of glass on the antenna nor rectangular coppper,
but it is a starting point. The azimuth pattern looks very good
according to EZNEC.

Any thoughts?

Make sure the window is not coated (highly effient dual-pane glass
normally is coated to shield IR radiation). The coating is metallic.
