A massive reflector might work with normal power levels. A friend of mine who was a ham and lived out on Long Island NY bought a surplus weather ballon (some kind of metalized plastic) and used to let it up at night and point his UHF yagi at it and work guys all over the tristate area... till the police showed up and asked him to take it down. To people traveling on the LI Expressway it appeared to be moving and the police were getting inundated with UFO reports.
