LINE LOSS CALCULATOR

Here's a quick line loss calculator to use. Note: The simple program used for this web page gives a very close approximation for additional losses due to SWR.
Set Parameters as Desired
Line Type:
Line Length: Feet Meters
Frequency:  MHz
Load SWR:  : 1
Power In:  W
Results
Matched Loss:  dB
SWR Loss:  dB
Total Loss:  dB
Power Out:  W

Enter dB Loss Of Cable Per 100 Ft. At The Desired Operating Frequency

Enter Length of Cable in Feet

Enter Power into Cable in Watts

Enter Gain of Antenna in dBd
