Coax Attenuation Chart - Ham Manuals

* Note: Coax losses shown above are for 100 feet lengths. Loss is a length multiplier, so a 200 ft length would have twice the loss shown above and a 50 ft length would have half the loss. This multiplier factor is why you should keep cable installation lengths between radios and antennas as short as practical!

The role of coaxial cable in broadband networks , Cabling .

Because the coaxial cable in hfc networks provides so much bandwidth (up to 1 gigahertz, in some cases), it is important to evaluate how the performance of the cable varies across the spectrum. The signal loss or attenuation of a given coaxial cable is determined by three factors: resistance, dielectric material, and radiation.
