Shielded CAT6A keystones?

Can anyone recommend some decent shielded CAT6A keystones that can be bought online? I've found some that look promising but they're in the $10+/keystone category. Ones I've seen at half that price usually don't have much information that goes along with them or don't have decent pictures of the inside/housing. I'm probably making this more difficult on myself than I need to but I thought it couldn't check in with the forum. :D

Thanks.

It's more important to have shielding on the wire. A shielded jack will do little for you performance wise.

Just take a look at the tool less one's, you'll be fine. Wait for other people's input, I think most will agree with me.

While electrical services, telecommunications equipment, and all other low voltage systems are required to be bonded to ground per national and local electrical codes and industry standards for safety reasons; the specific need to ground screened and shielded network cabling systems is only a matter of performance. A properly bonded and grounded cabling system carries noise currents induced by electromagnetic interference (EMI) in the environment to ground along the shield, thereby protecting the data-carrying conductors from external noise. The shield also minimizes cabling emissions. It is these functions that afford screened and shielded systems their superior immunity to alien crosstalk and other sources of conducted or radiated electromagnetic interference.

I disagree. If one is using shielded cable by choice and they've chosen not to ground it I don't see why they went with shielded cable in the first place. Seems like a waste to me.

If you use shielded cable, you're going to want shielded connectors.
Leviton is one of many quality brands.

Thanks.

For long runs I plan to use F/UTP with shielded termination. For short runs (e.g., patch cable between patch panel and switch) I plan to use UTP with unshielded termination. If it's necessary I'll replace the UTP with F/UTP for the patch cable. This is for a home install.

That's fine, but all you stated is you wanted shielded keystones. You didn't say what was going to be on the other side, aka a grounded patch panel, which without it, it would be useless to blow extra money on the keystones. You still do get a level of shielding without grounding the wire. And how big is your house that you think you need to waste money on shielded cables anyways?

That is true. But I still plan to properly terminate the long runs of shielded CAT6A with shielded keystones.

The effects of leaving both ends of a foil twisted-pair cable ungrounded can also be verified using the previous experimental method. As shown in figure 8, the coupling between two UTP cables (shown in black) is still a minimum of 20 dB worse than the interaction between two ungrounded F/UTP cables (shown in blue). It should be noted that 20 dB of margin corresponds to 10 times less voltage coupling. Even under worst-case, ungrounded conditions, the UTP cable behaves more like an antenna than the F/UTP cable!

Why are you using STP in your house?

I like to over engineer things or perhaps I'm itching to drops thousands on a 10GBASE-T (http://www.utp-vs-stp.com) setup that I don't need? ;)
