Free space path loss calculator

The simple free space path loss calculator is given below. Simply enter the figures as described and press calculate to provide the answer.

It is worth noting that according to the IEEE "Standard Definitions of Terms for Antennas", IEEE 145-1983, the free space path loss is between two isotropic radiators. The calculator below is a path loss calculator because it includes the antenna gains. To make it a free space path loss calculator, antenna gains of 0 should be entered into both gain boxes.

Path Loss, signal received and power transmitting
Power Transmitter in Watt or under		Power of transmitter in watt.
Power Transmitter in dbm		Power of transmitter in dBm
Distance(km)		Distance from transmitting and receiving stations
Frequency (Mhz)		Transmitter Frequency
Tx Antenna Gain(db)		Gain of transmitting antenna
Rx Antenna gain(db)		Gain of receiving antenna (commerial antenna gain is around 10db)
Total Feeder Loss Tx (db)		Total feed loss (cable, filetrs, combiners, connectors ...) side transmitter
Total Feeder Loss Rx (db):		Total feed loss (cable, filters, combiners, connectors ...) side receiver



Results:
Path loss (db):		Free space attenuation
Path loss Total (db):		Total attenuation of signal
Signal received (dbm):		Signal power received from receiving equipment
Signal received (dbuV):		Signal voltage received from receiving equipment
EIRP from antenna TX (dbm):		Effective power transmitted of transmitting station(dbm)
EIRP from antenna TX (dbk):		Effective power transmitted of transmitting station(dbK)
EIRP from antenna TX (Watt):		Effective power transmitted of transmitting station (watt)
