Hi Alexander,

Just a thought you may want to try piano wire as an aerial. We have used it on all our robots and in the 4 years its been used on Big Nipper we have only had to replace it about half a dozen times. Once when THz cut it in half and once as I recall when it was severed by a washing machine but thats another story. I am not quite sure which string it is although G string comes to mind, but thats possibly just my mind!
