Radio aerial

[Shaolin]

I've just bought a home cimema system which has a radio with it. The radio is pretty good but tonight the signal has started getting a bit hissy at times, moving the approx 1m wire aerial that came with it helps, but I don't fancy doing this much.

Is there a simple wire aerial I can make to add to it, if so how? just extend the current wire? or is there more to it? I know they're only a few ££ to buy, but they are away in the shops and I have lots of bits of various wire sitting around not doing anything.

Ah - ok, thanks for the reply, a bought one it is.
