Sometimes that's not even required...I lived in a valley surrounded by high 
hills and 2800ft mountains...by pointing my "suburban" antenna toward the 
west at that 2800ft mountain, I recieved tv signals originating from the 
southeast..
Pointing the antenna at the tv signal got the station, but with two or three 
ghost signals, which lead me to a search for one of those ghost signals..
I often thought of placing an antenna on a nearby hill and doing just what 
Craig has asked...I don't think his passive idea would work as well as a 
transverter.
... Tough guys don't have pillow fights.
