Re: How to find out the operating frequency of a Co-axial ca
If I get it right,
coaxial cables have not such as "operating frequency". Propagation in coaxial cables is TEM, which has no cutoff frequency. You only have to deal with it's attenuation per longitude wich increases with frequency and will made certain models unable for certain frequencies.
Only if frequency is very high, TE o TM propagation may occur and made the cable unusable. But this is above 20 GHz for usual commercial cables.
Let's say, if you have a short enough coaxial run, any cable will do.
I'm I right?
