For a cable length of 200 ft using Series 11 cable, what is the calculated cable loss?

The calculated cable loss for a given length of Series 11 cable depends on its specific attenuation characteristics at the frequency being used. Series 11 cable is known to have a specific dB loss per 100 feet, which is approximately 3.98 dB at 1000 MHz, for example.

For a cable run of 200 feet, you would use the formula for cable loss:

Cable Loss (dB) = (Attenuation per 100 ft) x (Length in ft / 100)

Using the approximate loss value, the calculation would look like this:

Cable Loss = 3.98 dB/100 ft x (200 ft / 100) = 7.96 dB

Therefore, the correct answer is 7.96 dB, which aligns perfectly with the calculated value for the specified length of cable. This precision in calculation is crucial for ensuring optimal signal integrity in broadband installations.
