Online Calculators

Click on any of the links below for more detailed information:

  • System Operating Margin (SOM) – Calculates the system operating margin which is the difference between the signal a radio is actually receiving versus what is needed for good data recovery.
  • Free Space Loss – Calculates the free space loss which is the transmission loss between two antennas.
  • milliWatts vs. dBm – Converts milliWatts to dBm and dBm to Watts.
  • Downtilt Converage Radius – Provides the downtilt coverage radius by taking half of the beamwidth in each direction of the downtilt angle from the height of the antenna.
  • Antenna Downtilt – Calculates the distance or tilt angle by providing the base height, remote height and either title angle or distance.
  • Fresnel Clearance Zone – Calculates the radius of the fresnel zone at its widest point as well as 20% blockage by providing the distance and frequency.
  • Latitude/Longitude Bearing – By providing latitude and longitude of a base and remote site it will provide the degrees from each site and distance in miles.
