Free space loss calculator

Use the free space path loss calculator to predict the strength of a radio frequency signal emitted by an antenna at a given distance.

Pasternack's Free Space Path Loss Calculator calculates the loss in dB between two antennas where the gain, distance and frequency are known. Loss increases with distance, so understanding the FSPL is an essential parameter for engineers dealing with RF communications systems. For example, if you wish to input "", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes. Path loss usually refers to attenuation of power that is radiated by the transmitter as the distance increases, especially in the field of telecommunication. When a signal moves from a transmitter to a receiver through a vacuum or free space without any hinderance or obstacle blocking its free path, this reduction in signal strength is referred to as free space path loss FSPL. To calculate an FSPL's value, one must also discount any possible reflections or other obstacles that might occur.

The signal strength that is lost as a signal moves through empty space is known as the free space path loss. Typically, its value is determined by discounting any potential impediments or reflections in its path. The loss between two isotropic radiators in free space, as stated as a power ratio, according to IEEE standards. It's measured in dB. MHz GHz. Result Free Space Path Loss. Click here to view image.

Additional Resources: Our Antenna Beamwidth Coverage Calculations is a unique tool to assit in calculating the maximum coverage based on antenna half-power beamwidth. Here is a field intensity calculation calculation tool to help determining the actual field intensity or power density at a given distance Antenna Factor and Gain Calculations Useful formulas for RF related conversions dBm to Volts to Watts conversion. High gain, low VSWR, and rugged design make this dual ridge horn antenna excellent for both immunity and emissions testing. This tool will calculate the maximum coverage that the antenna will cover from a specified distance and antenna's half-power beamwidth. Toggle navigation. Free-Space Path Loss Calculator. This calculator is used to predict the theoretical attenuation between two antennas in free space by entering the distance, frequency, and antenna gains.

The free space path loss is used to predict the strength of a RF signal at a particular distance. This is a theoretical value, as in the real world, there are many obstacles, reflections and losses which need to be accounted for when estimating the signal at a location. However the FSPL is a good approximation for estimating the loss of signal when propagating through free space. In the above calculation, the free space patch loss calculator takes in to account the gain on both the receiving and transmitting antennas. The gain of the antennas offsets the loss by a certain decibel value. If you ignore the gain at either end i. We have also assumed that the rf signals will be propagating in air. If they were propagating in another medium this calculator would not give the correct result. Free Space Path Loss Calculator. The free space path loss is the loss in signal strength of a signal as it travels through free space.
