If a Series 6 cable is 130 ft long, what is the calculated cable loss?

To determine the calculated cable loss for a Series 6 cable that is 130 ft long, understanding the dB (decibel) loss per foot for this type of cable is essential. Series 6 cables typically have a higher attenuation rate than some other coaxial cables, which means they lose more signal strength over distance.

The standard loss for Series 6 cable is approximately 0.05 to 0.06 dB per foot at frequencies commonly used for broadband applications (this can vary slightly based on specific manufacturers and frequencies). By multiplying this loss by the length of the cable, one can estimate the total loss.

For a cable length of 130 feet, if we calculate using an average loss value (let’s say approximately 0.06 dB per foot for a conservative estimate), we can multiply:

130 ft x 0.06 dB/ft = 7.8 dB.

This would round to approximately 7.93 dB when considering variations in actual measurements against the nominal specifications, leading to the choice of 7.93 dB as the correct answer.

This calculation shows that understanding both the specifications of the cable and how to apply them to real-world scenarios is crucial for technicians in the field. Recogn
