VSWR Calculator

Measured Forward Power: Watts
Measured Reflected Power: Watts
Cable Type:
Frequency: MHz
Cable Length:
Cable Loss = dB
Measured VSWR = ratio RL dB
VSWR at antenna = ratio RL dB
Power into/at antenna = watts
Power reflected from/at antenna = watts


Maximum Power rating for RG213 cable is 250 watts taking into account environmental de-rating.
