Web29 mei 2024 · How far do AM radio signals travel? Useful daytime AM service is generally limited to a radius of no more than about 100 miles (162 km), even for the most powerful stations. However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called “skywave” propagation. WebDuring the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions and quality of radio receiver used. Improved signal propagation at night allows the reception of much longer distance signals (within a range of about 2,000 km or 1,200 miles). Web27 jan. 2024 · For broadcast FM radio, you'll need an antenna (a) in a high location, so receivers can clearly receive your signal; (b) high power, usually on the order of kilowatts.
