"U" = "Utility" [edit] or "Universal". Nothing more or less.

Don't let it worry you. Some manufacturers include the "/U", others do not. It's pretty much irrelevant now.

I understand it to mean "Underground". You can burry it. Not all sheaths are able to do that.

Amazon.com : RG6U Outdoor Direct Burial Coaxial Cable, 18AWG Solid Black, 1000 ft Spool : Digital Coaxial Audio Cables : Electronics

No. If coax is specifically rated for underground, it will be labeled as "Direct Burial".

If you contact Belden, for example, they will give you the same answers.

Yes, that's what the link says. RG6U is Direct Burial.

Yeah, and, thanks to Amazon's suggestive selling, here's a direct burial RG6 that doesn't have the "U" (http://www.amazon.com/18AWG-Direct-Burial-Outdoor-Coaxial/dp/B00C9Y2N0U/ref=pd_sim_sbs_e_5) and here's an RG6U that isn't rated for Direct Burial (http://www.amazon.com/Southwire-56918445-500-Feet-Shields-Coaxial/dp/B0069F4H3G/ref=pd_sim_sbs_e_1)

If you go to that company's website for the product you highlighted, they have RG6U coax that is both rated and not rated for Direct Burial. So much for that as an example. Like I said, the "/U" is irrelevant.

For example, compare the nomenclature and specifications for Belden's 1694a (utility) and the 1694WB (Flooded).

Both are called "RG-6/U" but only one is rated for Direct Burial.
