Chapter 3. Coaxial Cable > Coaxial Cable Model

3.2. Coaxial Cable Model

Traditionally, the only attention that has been paid to signal attenuation has been the use of different types of coaxial cable. The primary parameters for twisted pair cables have been published, but similar information is not available for coaxial cables. To better understand the effects of termination and branch splitting when trying to identify a suitable transmission system for a high-throughput home network system over existing in-house TV signal wiring, we have attempted to estimate the primary parameters for coaxial cable. These estimates are based on cable loss measurements as well as cable physical dimensions. They are to be verified and improved by further experiments and measurements.

Signal attenuation of typical coaxial cables at a few different frequencies are summarized in Table 3.1. Attenuations are less than 10 dB at frequencies below 750 MHz for a coaxial cable of 100 feet. These cable losses, Ac, can be modeled by the following expression of two constant parameters.
