Customer Questions & Answers

Is this cable DirecTV approved?

Asked by: Greg
Here is the REAL answer. Yes, it will work on CERTAIN satellite systems, and no it is not Directv Approved. Here is why it will work on some systems. If you have a SWM (single wire multiswitch) system, the only line, or 2 that SHOULD be solid copper is the Genie or the line with the 21v Power Inserter. The reason why I say Genie is because the new HR54 models have a built in 21v power inserter. The voltage required to power the LNB on the dish is carried thru the center of the cable. Copper has less resistance than steel. The mini clients do not send of receive voltage, only signal, which is carried on the outer edge of the cable. Copper clad steel cable works JUST AS GOOD for the minis on a SWM system. Your older high def systems with 4 cables coming down from the dish, those lines should all be solid copper as each box transmits voltage. That is the REAL answer, been doing this a long time

Rated 5 out of 5 by from Excellent product!... Excellent product!

Rated 5 out of 5 by from Great Upgrade Cable From RG-59 I used this cable throughout my home during a complete re-wire of my cable and internet lines. I ran two lines of RG-6 quad-shield coax cable to each bedroom and to the living room as well, almost 600 feet total of cable was used. I was upgrading from dual-shielded RG-59 and couldn't be happier with the outcome. Before this re-wire, I could only have 3 cable lines in my home because the cable wouldn't allow for more. Not to mention I had to have an amplifier on 2 of those lines. Not with this new cable! No amplifiers, no poor signals, and 8 lines installed and ready to use. This cable is even higher quality than the RG-6 my cable company uses. I highly recommend this cable for a professional grade installation.

Rated 5 out of 5 by from HD Compatible Coax Cable This is excellent coax cable. The cable is rated for 3GB which is required for HD. The box nor any references at Home Depot show the bandwidth of the cable. I researched the cable on the manufacturer's website to ensure it was capable of 3GB bandwidth. Maybe this information will help someone.

Rated 5 out of 5 by from Good Stufff I found the cable itself of excellent quality and is the latest iteration of 4 layer wrapping for preserving signal strength. That said it is a little hard to work with installing compression fittings, which are the latest and best terminal ends available. I think the consumer should consider experimenting with a trial piece before making a cable you intend to use, what I wound up doing, I set up a cable trimming tool to expose the first 1/4" to the copper core, the next 1/4" set the tool up to cut thru the 1st foil layer, and 1st wire wrap, which leaves the 2nd foil and 2nd wire wrap intact (if the trimming tool has a third blade remove it) ,THEN before you attempt to insert the fitting, warm the outer housing with a heat gun, to facilitate sliding the connection on. This seemed to work well, but is no guarantee of your results. I am now saving approx. $100.00 a month using an antenna over the service I was using, not as many channels but the picture is just as good.
