Existing coax operates at which frequencies?

The main idea is that coax has a defined maximum operating frequency, which is the highest frequency it can carry with acceptable performance. In outside-plant and CATV-type installations, you commonly see three typical upper-frequency ratings for existing coax: 450 MHz, 500 MHz, and 750 MHz. These reflect older lower-band service up to about 450–500 MHz and the more common upper limit of around 750 MHz for many 75-ohm cables used to support higher-bandwidth signals. So existing coax is generally considered to operate up to these frequencies, depending on the specific cable type and age. The other frequency sets aren’t as representative of the typical field coax you’d encounter.
