Re: CB/SSB Radio Use - I have a few questions.
RG 8X is common.
I have a buddie in the marine radio business and he gets me some real heavy cable. It is 1/2" diameter. Its big like a rg 218 but i dont think that is it. The 218 is a 50 ohms cable.
You could probably find a 50' roll made up ready to go. If 50' will make it.
But as far as the coax goes it is a rg8
you could probably ebay some of it
Who are you going to serve today?
