    Comments about RadioShack 100-Ft. RG-8/X Coax Cable in Pull Box:

    Amateur Extra Class so I have some past coax experience. This coax is some custom size. It does test out to be 50 ohms. Center conductor is heavy multiple strands. Shield is <50% copper braid with foil wrap. Braid is just enough to solder connector. Outer jacket is very thick/heavy and over-sized for RG8X. Outside diameter is too large to fit UG-176 reducer for PL259. Had to drill out UG-176 for proper fit. Overall this stuff is bargain at the price but will require more effort to install connector.

    This is what you get - RG-8X

    Comments about RadioShack 100-Ft. RG-8/X Coax Cable in Pull Box:

    Please realize, what you are ordering is RG-8X cable. Not an RG-8 or RG-58. For price, what I received is excellent. That said, quality does not compare to Belden equivelent costing over twice as much.

    First, when you order this item, you get an acknowledgement that you've just ordered an RG-8U, item #2780020. In fact, you get several correspondence from Radio Shack, and item keeps changing between the correct one and this one. What you receive IS the correct item.

    To make the matter more confusing, spec on this website says the impedance is 14.2 ohms. The box correctly identifies the producct but the cable itself does not say anything about it being RG-8X. It just says 16AWG.

    The cable has a regular PVC jacket, so it is NOT for heavy duty use. But for casual use, it'll be just fine. The braid coverage is about 50% but there is an inner aluminum foil shield. So no concerns over leakage or noise pickup. (which doesn't happen anyway) The dialectic is foam type. The center conductor is stranded. The physical measurement matches that of Belden's spec, so the impedance is somewhere around 52 ohms. There is no way this is 14.2 ohms.

    I have not had a chance to do more detailed examination of this cable. But, I have no doubt this cable will work just fine for my intended use. I intend to use it for an outside HF dipole and for a year or two. I probably won't use it for higher frequencies but for it having foil shield, it may actually have lower loss than more expensive and proper RG-8X.

    I'll be buying more of this actually. This is only 25 cents a foot. It'll work just fine for HF, and likely higher. I expect it'll last for few years. After that, anything is possible with all but highest quality coax anyway.

    I think there is so much confusion over what this actually is, this product is unfairly rated. Mis labeling by Radio Shack didn't help either.

    Hope this review is helpful.

        The cable doesn't even say it is rg-8x on it anywhere. Wont fit any connectors. Size should be .24 and is actually .27 Returned to store don't waist money on it if you don't have to.

          Comments about RadioShack 100-Ft. RG-8/X Coax Cable in Pull Box:

          Some of the other reviews are so confused. This is RG8X coax, not RG8. Not as lossy and the smaller RG58, not as low loss at RG8. It is not LMR400, but it's not 75cents a foot either. Good for lower hf, up to 30mhz or so. Good for jumpers at VHF and UHF. It can handle 1.5KW legal limit into a fairly matched antenna.

          Better than RG-58/U!!!

            Comments about RadioShack 100-Ft. RG-8/X Coax Cable in Pull Box:

            RG8/U (also called RG8M (mini RG8) is a good choice if you want low losses, easy handling and a cheaper cable that RG8/AU. RG8/U has a diameter of 0.242 inches. Regular RG8/AU has a diameter of 0.405 inches. As you can see, RG8U has a smaller diameter than regular RG8A/U. In order to install RG8U on to a PL259 plug (Cb Connector), an adapter has to be used. The adapter screws into the PL259 plug and acts as a shoulder for the RG8U. Tha adapter is Radio Shack part #278-204. The price is 2 for $2.99. It seems that some of the other people giving reviews did not know this when they faulted that RG8U for not fitting a PL259 plug. Here are typical (in General) loses measures at 50Mhz (per 100 feet) , for 3 popular CB coax cables: RG58/U 4 db. RG8U 2.2 db. RG8/AU (the big coax cabe) 1.7db. As you can see, RG8U is a pretty good compromise for the ocassional CB hobyist that is operating a legal set. If you are running a CB set with about 50 or less feet, RG8U would work fine. Admittedly, the best CB cable is RG8/AU since it has the least loss. I look st RG8U as a good compromise. I use RG8U in my truck and in my home and I am quite satisfied. For the money, it's a very good cable.

            Best Uses

            • Ok For Indoor Patches

            Comments about RadioShack 100-Ft. RG-8/X Coax Cable in Pull Box:

            This cable is RG8X, also known as RG8U Mini. There are standards for RG8X, but NO MIL STANDARD. There are standard connectors that fit this coax perfectly, but of course NOT the RG213 (RG8) connectors. I have run several hundred watts through this cable for many years, without problem, but it has all been indoors. I can't say how the jacket will hold up outdoors.
            The only valid con is, the shielding is marginal. This might lead to unwanted EMI problems. If that's the case you are better off using a double-shielded cable.

                    The last reviewer is confusing RG8X with RG8. These are two entirely different cables!! RG-8X is closer to same size as RG-59 cable. A PL-259 requires the RG-59 adapter to use RG-8X. RG-8X is a miniature version of RG-8; it has good power handling ability and is easier to handle. The tradeoff is a bit more loss.

                    Comments about RadioShack 100-Ft. RG-8/X Coax Cable in Pull Box:

                    Diameter will not fit PL259 Connectors. It is for indoor use only. Very poorly manufactured and mis-labled RG8U coaxial cable. The Impedance is not 50 ohms and would better be used for hookup wire or cleaning out a toilet blockage. Radio Shack is really out of touch in this area, unknowledgable or just desperate to sell anything no mater what. It is obvious no one at radio shack has ever held a piece of real RG8U coax or RG213 Andrews or Belden coaxial cable. My God, the cable wont even fit the connectors that radio shack sell for it...RG8u coax is 49.7~51.3 ohms just to show their sales capabilities, they call it 14 ohms impedance, what a tradgety of ignorance and a total waste of time.The cable is going back to RS, it was misrepresented with many obvious errors, it is junk and should not be purchased by anyone who is looking for a real 50 ohm RG8U coaxial cable. By the way, the pull out box is a joke. I guess the givaway was the 4 pound shipping weight...Duh!

                          This product is obviously mislabeled. RG8U is common 50-ohm coax used in radio communications. According to the Specification page, this product is 14.2 ohms, clearly NOT the impedance of the well-known RG8U cable. DO NOT PURCHASE if the application requires 50-ohm impedance.
