Q

What is the diameter of 10B2 coax cables?

I've got a problem with cable attenuation. Can you tell me what the diameter of 10B2 coax cables are?

 

Wow, now there's a question that takes me back a few years! 10B2 cable follows the RG-58 A/U (or RG-58 C/U) mil spec. Here are the numbers as obtained from
