Right now, I use 11cm stripped coax :) But that's because I live 600 
meters from the broadcasting tower. This actually gives me the best 
reception. The mini antenna that came with the thing worked quite well, 
but the wire was a bit short.

Besides that I did use a powered antenna for a while, without the power 
connected, because it actually dampens the signal. That worked quite 
well for a while. Using it powered, with an external power source, 
actually made it much worse.
