RG58 50 ohm coax has done me well over the years albeit shorter runs.

Can anyone tell me what 50 ohm coax is available with the same physical properties of RG58 ie size but with the electrical properties of something like RG213.

I basically want to use a long run of low loss coax similar to RG58 and if i use RG58 for this i believe it will become quite lossy.

Has to be good quality even if bit dearer.

to get what you require ....low loss and in a roughly same size 5mm aint cheap but they are out there for example https://www.nevadaradio.co.uk/cables-le ... -aircell-5

I've been using this for a few years;

compare the specs, not a lot between it and the expensive stuff. Its nice to work with and attach connectors.

What is "long run" on your mind?
