Link Budget Calculations

This animated video goes through link budget calculations, free space path loss calculations and how wireless signals propagate as they go from a transmitter through a coaxial cable system into an antenna over the air and to a receiver.
This also goes through system gains from antennas and amplifiers and system losses from coaxial cable, free space path loss, connectors. It discusses why the decibel is used for link budget calculations and how we convert from watts to dB.
