Calculating radio signal distances

In summary, by knowing the frequency, effective radiated power, height above average terrain, radiation center above mean sea level, and radiation center above ground level of a radio signal or tower, it is possible to estimate the range of the signal using a link budget calculation. However, the accuracy of the prediction will depend on the specific band being used. The Longley-Rice model is commonly used in the VHF and UHF bands for television in the USA.

If I know the:

  • Frequency
  • Effective Radiated Power
  • Height Above Average Terrain
  • Radiation Center Above Mean Sea Level
  • Radiation Center Above Ground Level

of a radio signal / tower, is there a way to determine the rough range of the radio signal?

A lot has been written about this and the accuracy of any preciction will depend on the band you are working at. You need to google "link budget" to get an idea about the problem.
This link could give you an idea of what you want to know

Related to Calculating radio signal distances

1. How is the distance of a radio signal calculated?

The distance of a radio signal is calculated using the formula: distance = (speed of light x time) / 2, where the speed of light is 299,792,458 meters per second and the time is the round-trip time of the signal.

2. What is the speed of light used in the calculation of radio signal distances?

The speed of light used in the calculation of radio signal distances is 299,792,458 meters per second. This value is constant and is denoted by the symbol "c" in the formula.

3. How accurate is the calculation of radio signal distances?

The calculation of radio signal distances is relatively accurate, with an accuracy of up to 99.9%. However, factors such as atmospheric conditions, interference, and equipment limitations can affect the accuracy of the calculation.

4. Can the distance of a radio signal be calculated for any type of radio wave?

Yes, the distance of a radio signal can be calculated for any type of radio wave, including AM, FM, and microwave signals. The formula for calculating distance remains the same for all types of radio waves.

5. What are some practical applications of calculating radio signal distances?

Calculating radio signal distances is used in various fields such as telecommunications, astronomy, and navigation. It helps in determining the location of objects in space, measuring signal strength and interference, and determining the range of communication for different devices.
