Broadband coax operates at what frequency?

Broadband coax is specified to carry RF signals over a practical range, and the standard building-distribution coax is designed to work well up to about 300 MHz. This upper limit is chosen because, as frequency increases, coaxial cable losses rise and shielding needs become more demanding. Keeping to around 300 MHz allows multiple channels to pass with acceptable signal levels over typical run lengths using commonly available cable and connectors. Lower frequencies like 100 MHz would limit the available bandwidth, while higher frequencies such as 600 MHz or 1 GHz would require more expensive, lower-loss cables and more precise components to maintain performance. Therefore, 300 MHz is the best fit for standard broadband coax in many OSP design contexts.
