Sent DB2 back: Homemade HDTV antenna idea?

I sent my DB2 antenna back.  Didn't perform any better
IN the house than cheap rabbit ears.

So..... I recognize that what I need is an OUTSIDE
antenna and one as high as possible.... matter of fact
these two parameter are more im****tant then the
'design" of the antenna I gather?

So..... what if I take some coax and strip off a long
section so that the inner wire is bare...no ****elding.

Then I get this "end" outside ... maybe up an outside
wall..... or along a banister on my apartment.

This likely to work well? It would be cheap anyway!
