If it is what I am thinking it is, RG6U is quad shield where as RG6 is shielded twice. We use CommScope.debbytcr said:Can anyone tell me the difference between RG6 and RG6U coaxial cable?
What is a good quality brand?
bhelms said:RG-6 is a generic term, and is best interpreted as "sort of like". The "slash" number is a type designation, and that suffix came from the original, now obsolete, military "slash sheets". So RG-6/U meant something specific as to construction and specifications. Thus using just RG-6 essentially means that the cable in question somehow deviates from the original /U (or /A, /B, etc.) specification in some manner. /U actually means "multiple uses".
Here is a link to some information on the numbering scheme:
See also this topic in Wikipedia for another explanation, then follow the "coaxial cable" link in that article to get to a specific listing of RG type cables. You'll note they are (almost) all /U...
As Iceberg noted, quad shield is usually marked as such, and it is also designated as such, e.g., RG-6/UQ...
EDIT - I agree with Mike500 that RG-6/U (and ALL coax for that matter) is unbalanced, but that is not what the /U means.
Well, like I said in the post before yours, I have gotten higher signal strengths using some RG-59 cables than some RG-6. A good RG-6 is always better, but the best RG-59's are going to be better than the worst RG-6's.Barry Erick said:RG59 comes in several flavors, from those with very high signal loss and just one bare wire running instead of a braid that the better ones have. Those with a solid braid are excellent, but still nothing like the cheapest RG6.
