Coax cable

[Grumps]

Now then, is RG59 the same as RG59/U? What does the suffix indicate? I have searched for lists of cable sizes, but they all seem to have the /U. Are there any other suffixes?

[Rob Morley]

Does the U mean it's UV stabilized?

[Chipmunk]

/U means universal usage. I believe the black sheathed stuff IS UV stabilized but that's apparently not what the /U means:-) RG59/U would be suitable where RG59 is specified, they probably meant the former anyway.

Also, the RG stands for Radio Grade, [I assume as opposed to audio grade]

What do you want to use the cable for?

A colleague at work wanted to know if he should order RG316 or RG316/U. As it happens, I don't think he could find any RG316. (but the co-ax connector data said use RG316)

[Peter Crosland]

Noted. It is a specialised microwave cable often used for 2.4GHz. Unless he has the right tools he will have a lot of trouble terminating it correctly. It would be sensible to buy a length with the connectors qalready fitted. It might cost more but it should ensure it works. AFAIK there is no practical difference that he needs to worry about.

We have the correct tools. He is just using the last few metres of the current reel, and needs to get some more. Of course, nobody remembers where this reel came from.

This might be what you are looking for but you should be able to get it cheaper elsewhere.

confusion was that the current reel says RG316, and all he could find was RG316/U.

[Peter Parry]

The suffix /U is part of the Joint Electronics Type Designation System code and when used with components such as cable it simply designates an item meant for general purpose use. RG58 and RG58/U are exactly the same.
