Most domestic microwave ovens operate by emitting a very high power signal in the 2.4 GHz band. Older devices have poor shielding, [10] and often emit a very "dirty" signal over the entire 2.4 GHz band. [a] This can cause considerable difficulties to Wi-Fi and video [12] transmission, resulting in reduced range or complete blocking of the signal.
The dish had to be pointed directly at the satellite, with nothing blocking the signal. Weaker signals required larger dishes. [4] [5] [6] The dishes worked by receiving a low-power C-Band (3.7–4.2 GHz) frequency-modulated analog signal directly from the original distribution satellite – the same signal received by cable television headends.
