How far do fm radio waves travel
WebFootnotes: Footnote 1: The wavelengths of AM radio signals vary from a maximum of 555 meters (1821 feet) at 540 kilohertz (kHz), the lowest AM carrier frequency used in the United States for broadcast stations, to a minimum of 176 meters (579 feet) at 1700 kHz, the highest carrier frequency at the upper end of the AM expanded band. In contrast, the … WebWe invented a new, inexpensive device to measure distances up to 1.5km (about 1 mile) with accuracy about ±5 Meter (15 feet). The use of radio waves makes it possible to measure without the target being in sight.

Web27 apr. 2024 · They travel at an approximate speed of 186,000 miles per second in a vacuum. Unlike radio waves, sound waves cannot travel through a vacuum. They can only travel through a medium. In other words, without a medium, you cannot have sound. Radio waves do not necessarily need any medium for their propagation. WebOur Own GMRS Range. The estimates below are based on the author’s own experience using GMRS radio in a variety of settings. They assume a 5 watt handheld, 50 watt mobile, 5/8 wave mobile antenna with 6 dB gain and 5/8 wave, 6dB gain omnidirectional base antenna at 50′.
