I know with a yagi antenna that putting it next to metal will cause parasitic coupling and detune the antenna. Starlink using what is essentially aesa, does this negate the issue? If so I don't see how because even traditional phased arrays are susceptible to parasitic coupling. I ask this because traditional transmitting antenna systems you always want to keep them away from metal. However it seems to be the consensus that metal roofs do not effect starlink. If this is truly the case then why?
Also if the antenna has its own reflector between it and the roof, wouldn't that make the roof completely invisible to the antenna?
There are reactive / out-of-phase waves, but they can't transfer any energy (by receiving them you're turning them in-phase).
The most likely way of an EM wave getting through a metal plate is the metal plate not being a perfect conductor (duh, metal usually has non-zero resistance)
