Hello All,
I have an equipment where 50 Ohm RG58 coaxial cable is used for transferring up to -2 kV from one side to another one (4 m cables). Actually this is shv bnc cable. It seems that cable is broken and I have spare but RG59 (75 Ohm), 50 Ohm I'll have to buy which is quite expensive as it is SHV not normal BNC.
My question is - can I just replace 50 Ohm with 75 Ohm cable?? It's just DC signal, high potential but almost no current so I guess I can, but want to get your opinon. According to wiki https://en.wikipedia.org/wiki/BNC_connector connectors 75 and 50 Ohm should fit to each other.
Right now I'm not close to equipment, so want to be sure that I have everything when I go onsite.
Thank you very much for feedback.
