  • VSWR and Return loss calculations

    VSWR (Voltage Standing Wave Ratio) is the measure of how efficiently RF power is transmitted and is expressed as Return Loss (RL) is a amount of power that is lost to the load and returns back to the system as a reflection typically expressed in dB. A high % loss means more power is lost at the load.
