How does increasing the quality of a coaxial cable affect its attenuation?

Improving the quality of a coaxial cable typically results in decreased attenuation. Attenuation refers to the loss of signal strength as it travels along the cable. A higher quality coaxial cable generally has better materials used for its conductor and dielectric, as well as improved shielding.

These enhancements allow the cable to transmit signals more efficiently by minimizing energy loss due to resistance and external interference. High-quality cables typically have lower resistance, which reduces the overall loss of signal as it travels through the cable. Therefore, as the quality of the coaxial cable increases, the attenuation decreases, allowing for stronger and clearer signal transmission over longer distances.

While variations in frequency can affect attenuation, the general principle remains that higher quality cables are designed to minimize these effects, resulting in an overall decrease in attenuation during normal use.
