Title: prove that not all Aliexpress sellers know what they are selling
Post by: GreenHW_GUY on October 14, 2018, 10:21:01 am

I was asking the seller to get the right info, because the info on the page was not right, and the answer didn't help me more. You can try to find the error

RG58 is 50ohm (or 52), so either they meant to write RG59, or they got the resistance wrong.

I know that why I don't get any good info Info from the seller, and all with Coax on aliexpress write the same, when you looking for the 50z \$\Omega\$ COAX, it was only for hobby project, my ham radio I use some highter Quallity Cables

They don't use the RJ-59 designation (or at least properly) in China. They mark it based on wire diameter and connector type and not by the impedance standard. So yes, that cable is likely exactly as specified, it really is a 75 \$\Omega\$ RJ-58.
