I'm installing a network bridge to link two buildings, and I plan to build a small enclosure on the roof of each to house the hardware. The hardware worked fine in tests on the roof but not inside the reinforced masonry building.
The question is, what would be a good material for the line-of-sight side of each enclosure? Metal is obviously out. So is having an open face; birds will nest and rats will chew. What about wood, or the various plastics? Any of these stand out as particularly transparent to wi-fi signals?
I'll be installing a 5g bridge, and may also use 802.11 b/g/n devices, if wavelength is a factor in material choice.
