In Reply to: Video/Audio Cable Question posted by G_String on July 13, 2000 at 12:30:55:
This is a pricy suggestion, but it works. Belden makes model 1694A RG-6, SDI/HDTV coax for hookups like you've got. This is part of their "Brilliance" line of cables; it can carry a 3 gHZ signal with little degradation over long distances. I'm using a much shorter run and notice a marked improvement in picture quality. Read the specs at Belden's website. HAVE, Inc. (www.have.com) sells the stuff, but there are other distributors. They mount Canare F-connectors that are excellent. If the price is too high, look at Belden 1694A quad shield.
I am getting confused by the terminology (no pun intended). I went to the Belden site and found no "Brilliance" 1694 cables and no quad shielded 1694 cables. Their site is hard to negociate so I may not have got into the right part. I am familiar with 1694A RG6 cable,without all the sub classes. The 8281 coaxial is a higher priced cable. The Canare L-4CFB or L-5CFB is supposed to be superior to 8281 according to the Markertek catalogue I have. Please expand this discussion for outsiders if possible. Thanks.
"Brilliance" is Belden's new marketing term encompassing their whole line of AV cables. The 1694A RG-6 SDI/HDTV (Serial Digital Interface) is what studios have been using to upgrade to Hi-Def TV broadcasts (go to bettercables.com website and click on "press release" for Belden. It talks about this cable). It can pass signals out to the gigahertz range with little loss over long distances. The "regular" 1694A is not quite as broadband, if their website specs are to be deciphered correctly. I got most of this info from e-mailing Belden directly; they're good about e-mailing responses back. The Canare you mentioned is also supposed to be good, but there are differences in shielding and bandwidth capacity. The 1694A SDI/HDTV is not cheap.
I believe the 82248 (available through RS's online site) is also RG-6 and is a very nice cable to try if you don't want to spend the cash for the "Brilliance". I have no idea how it compares to the 1506.If you do try the "Brilliance" and it's truly-named, drop a post back here -- it might spur me to try some for my own setup.
I heard about the Belden 1694A RG-6 SDI/HDTV coax being used by broadcast studios for Hi-Def broadcasts, so I thought I'd give it a try. (If the studios are using it, why not me?) I'd used the "regular" 1694A for a while; it was cheap, and so were the F-connectors. The newer stuff I had done up with good Canare true 75-ohm connectors; a 25-foot run from satellite to receiver, then a four-foot run from receiver to TV. The picture was stunning. I tried it on a similar run from cable converter to TV; again, the picture improved. I've kept the newer Belden and satellite; got rid of the older Belden and cable converter. Prices were about $180 for the cable run and good connectors, about six times more expensive than the older Belden. It might be just "plain old coax" and not fancy interconnects or power cords, but since a lot of viewing is done through RF connections, it was worth it to me.
