I think it's time for a universal re-classification of coaxial cables.
It gets a bit silly when you can't just go by the RG number to select your cable.
I notice on the Belden site, that their RG11 cable is listed as only having a nominal loss of 12.37dB/100m (13.88dB max) @1GHz, whereas the Maplin RG11A/U has a loss of around
double that at 25.5dB/100m @1GHz.
As for ntl using Belden's RG6, which one of the
59 types of RG6 cable do they use?
