Hello!
I'm planning to build a parabolic reflector using aluminium net.
The kind of net i found is just a weave of aluminium threads, no
connnection between the threads. Is this going to reduce the
performance of the reflector?
The net is built of 0.4 mm thread and the hole size is 1.5 * 1.5 mm.
I'm planning to use the reflector on the 23 cm band.

If these work at 2.5 GHz, I think you'll be able to use about anything
as long as the parabola is correct. http://www.qsl.net/n9zia/wireless/
