MossieNET's omni-braai:

{joey} Here is the design of a back reflector I found at http://www.freeantennas.com/ The 2nd design does say copyright, but it was made available at the same site?

I haven't got down to building one myself, but I suspect that the mesh metal used on braai-grids should do well. The holes will help with wind and won't affect the RF as long as they're less than a quarter wavelength, i.e. make sure the holes arent more than 3 cm in diameter.
