[Repeater-Builder] coax notch

[steve]

Hi is there a fr,ee computer prog to work ot the lenghts of coax to make notch filters ?. Iam starting to put together a 6mtr repeater here in the UK, and need to play with coax to make a duplexer, can't afford the prices of a ready made one. I don't fancy using heliax, OK it works, but looks a mess and takes up so much space. So any ideas appreciated.     73     Steve Yahoo!
