Thought I'd share what my last project was, a home made Dipole.
It is made from 2m of 20mm aluminum tube, a 20mm conduit a "t" piece, 3 chair end caps, a couple of screws, a few pop rivets, a couple of terminals and coax to suit. All up cost me less than AU$40, and it outperforms any antenna I've had before.
This is it mounted to my hockey stick on the side of my house.
I know its a bit wonky, when I drilled the holes for the bracket I used my cordless and it wasnt on a straight surface.
