Best material for a cylindrical antenna reflector at 2.4 GHz

[david90]

What material would be best to use when making a cylindrical reflector (antenna) for a 2.4Ghz signal?

Material

At 2.5 Ghz the skin depth of RF signals is quite small so to keep down losses
it should at least be smooth , but aside from that there is probably little difference between conductors such copper or aluminum.

Best material is silver.

Most cost effective material is aluminum.

Best performance for the buck is copper.

The last post may be correct but the point is that it is only the surface which counts not the bulk.

Are you perchance making a parabolic reflector to enhance your Wifi?

There's lots of literature on the Web about it, including blueprints for shape and curvature, and full instructions. I built a couple myself, takes about an hour and can be done entirely in your kitchen. The most sophisticated material used is aluminum foil.

I stand corrected.

Silver-plated copper is best.
