Passive & Coaxial Cable Characteristics
Cable and Equalizer Formulas
1. Cable Loss Ratio
The ratio of cable attenuation at two frequencies is approximately
equal to the square root of the ratio of the two frequencies.
Example: To calculate the approximate cable loss at 55 MHz
when the loss at 450 MHz is 20 dB,
2. Tilt to Cable Loss
To convert tilt (differential in signal level between end frequencies
of the cable bandpass) to cable loss at the highest frequency:
Example: To calculate the cable loss at the highest frequency
when the measured tilt is 12 dB between 55 and
450 MHz
