3.4G feed horn dimensions ?

The 9cm's SG-Labs arrived yesterday and I'm cant wait to get going.

I've found on the G3PHO site a "Soup Tin" feed horn.

I've copied it and the SWR is in the green straight away :)

But what length should I make the waveguide section, it is not mentioned in the article ?

And what does a Chaparral horn actually do ?
