Making a hydrogen line Cantenna

[athornett]

At last I am having a go at making myself a Cantenna (a type of aerial made using old tin can - in this case designed to detect hydrogen on 1420MHz in Milky Way)! If this works it will demonstrate that I can make a full hydrogen line radio telescope for < £100!

This would be a great project to offer members of my local astronomy group.

This is something I've been thinking about for a while but never quite got round to so I'd be interested in the details, thanks.

-tenna is a bit of a stretch (unless frontend noise figures have exponentially remarkably improved since my day !)
-orn,  ie."canorn" would be better as it is more of a feed horn in the antenna proper Cos it still needs a dish as well, both for gain and resolution(beamwidth) 

nice project though, 

sorry, couldnt resist   good luck

No problem I will let everyone know ow how it does
