MechAg94 asked,
Could you just put a rough wire mesh on the inside of the sheet rock of the outer wall?
Good question. I suspect it depends on the size of the openings versus wavelength. Super-high and UHF frequencies are funny. I note that the holes in the microwave oven door screens are about 1/16th-ish inches, so obviously they can't get through that, at 2450MHz, 12 cm wavelength.
On the other hand, I was always fascinated by the fact that folks could use their cell phones on the elevators at work. UHF and SHF waves bounce around a lot and like mice, can sneak through small openings.
And on my third hand, I note that my over-the air TV reception gets boogered up when the trees outside get wet, so obviously, they reflect (or absorb) a lot.
Trouble is, I cut my teeth in radio when 50MHz was virtually the "edge of the universe" when it came to shorty-short wave communications. I was stunned when Son2 built a quad loop to receive the International Space Station conversations at 70cm (420 to 450 MHz).
Why, a person can't even shake a stick back and forth that fast.
So...long and short of it: I don't know the mesh size required, and offhand, don't even know the frequencies involved in satellite control/communications. I think they're on the "government band" around 800MHz, but my
Radio Amateur's Handbook is from 1986,
anno domini. Might as well be 1986 BCE.
When you start talking waveguides as opposed to good ole garden-hose-like RG-8U coaxial cable, I get lost.
