I am trying to understand how to choose a coaxial cable (for my current application, I need a 50Ohm coaxial cable that works reasonably well in the DC-10GHZ range). According to the table in section "standards" of Wikipedia, I would choose the cable with the fewer possible "max attenuation", eventually taking into account the size and rigidity of the cable (I don't care about velocity factor). But I don't known if this attenuation measure at 750MHZ does mean something about 10GHZ.
More practical related question:
Does the LMR200 perform reasonably well at 10GHZ?
What about RG402? (I've read somewhere this is the preferred option for 10GHZ radio ham, but I don't understand why).
