It has to be able to get rid of other microwaves pretty close to its own signal bandwidth; then it certainly won't have a problem with some low-frequency mains hum (unless it were so strong to drive the circuitry into nonlinear behaviour or something, but for that you would indeed need a huge antenna). | |
