Iam sitting here and doing some math with my ARRL-handbook. The Pringles-can that is a mix of a waveguide and nonconnected yagi don't match up with the math. The diameter is to small to work in the 2.48GHz span. So why does it work?? Does anyone know?? I made a Pringles-antenna and made serious measurements on it and it showed that the antenna is not good. It showed that the Pringles only came up to 2dBi gain in the front loob.

Ok Pringles don't work but how should a cheap good antenna look like?? I made a standard waveguide with a diameter of 85mm and made the same serious measurements on this antenna...and woops the gain was 8dBi.

The thing I would like to say with this is that if you would like to make a good antenna check the theori first...like the ARRL-handbook.
