Can I have few holes on the housing which does not allow leakage of 11 GHz signal outside from the housing? What's the maximum size of the hole which does not allow RF out @11 GHz? cheers, per_lube

Maybe it would be good idea to make it away from LO oscillating part, and put some absorbing material in the hole.
