Aircraft radar systems can interfere with radio astronomy when planes are in the line of sight of telescopes. Dynamic scheduling of observations can help mitigate this.

Common electrical appliances can produce RF noise. Implementing 'electromagnetic cleanliness' protocols for electronics around observatories is a mitigation measure.

Heavy industrial machinery and tools can cause broadband interference. Industrial zones are typically kept far from radio observatories to mitigate this problem.

Microwave oven leakage can interfere with radio astronomy observations, especially in the 2.4 GHz range. Observatory sites are equipped with RF monitoring to prevent interference.

The ignition systems of vehicles can create broadband RF interference. Ensuring vehicle-free zones around radio telescopes is a common mitigation strategy.

Cell towers emit strong signals in the RF spectrum, which can cause interference in radio telescopes. Mitigation includes implementing exclusion zones and RF shielding.

Satellite transmissions, especially those for communication or GPS, can interfere with radio observations. Using directional antennas that reject off-axis signals can help.

Wi-Fi and other wireless devices operate in frequencies that can interfere with those used for radio astronomy. Radio quiet zones can be established to mitigate this interference.

Commercial broadcasts can bleed into adjacent frequencies. Notch filters can be used to mitigate this type of interference.
