I wonder if keeping the foil on would improve the signal strength? It could only be used inside, but it might be worth experimenting with.

If the mesh gaps are better than ~ 1/10 a wavelength it makes no real difference. At 2.4 GHz this translates to about ½ inch ( ~ 12.5mm) minimum hence- anything better than that will be "seen" as a solid screen by the RF. Naturally more open designs are lighter & far less wind prone too.
