  • This short video shows how to install a crimp style BNC connector onto RG-58 50 ohm coax. Installation of other crimp style coaxial connectors will be similar. Note that the connectors are specific to the type of coax being used, and having the correct crimping tool is really a necessity. You can optionally (carefully) solder the center pin, and optionally finish up with some heat shrink tubing for clean professional look.

    The one thing this video doesn't mention that I screwed up (and that AVIVX's video does mention) is pushing the BNC connector down hard enough until you feel the snap of the pin seating. Otherwise the pin won't extend far enough for as solid of contact as desired with the mating connector.

    When we view some of these Do it yourself" videos, some of the contributors tend to go off the deep end, showing you their "shacks," listening to them talk to their barking dogs, and musings about their personal lives, all the while they are supposed to be "teaching" us something, like putting a connector on a wire. Your video was excellent: to the point, no unnecessary commentary, and detailed instructions.
    Even thought I wasn't in the market for such instruction, I found myself watching it to the end, just in case I may need it someday!
    Good job!
    Thanks!

    I learned how to do that about 35 years ago, putting BNC connectors on RG-58 style coax for "thin" Ethernet. The steps you showed matched up almost exactly with how I did it. I could not agree more on your point that you need to match the connector to the cable and then the tools to the connector. I had to work with Belden 8997 cable (I think it was) which was for air plenum use, basically almost like Teflon, no smoke during a fire. It was new enough that I had to use one crimp tool for the center pin and another for the outer crimp ferrule. Regular coax could use the same center pin tool but yet another for the ferrule.
    Nicely done video overall, just enough details, long enough without being too long.
    Take care, Sir!

    @dannelson8556 8 ปีที่แล้ว

    Very nice tutorial. I would like to point out, You forgot to mention the center pin on those BNC's is captive and that the pin should click into place when inserting the coax into the connector. Once the pin is inserted you should not be able to pull the coax back out if you can then it's not installed all the way.
    Also an easier way to install the connector under the braid is to fan the braid by gripping the coax jacket just under the trim point, place the connector on the dielectric just above the braid and carefully rotate the dielectric in a circle by flexing the dielectric this will fan out the braid uniformly, much harder to explain than actually do.
    I like to use 4-1 adhesive lined heat shrink as a strain relief. I also add a tiny piece of thinner colored heat shrink over the thicker adhesive lined stuff on both ends for color coding. Makes it easier to quickly identify what test lead is attached to what device. For example on my bench red is always the input to sensitive test equipment such as spectrum analyzer inputs.. I always use green for outputs from signal generators, yellow is always DUT .... Anyhow you get the idea

    • @w2aew
      @w2aew  8 ปีที่แล้ว

      +Dan Nelson Not all BNC connectors have the captive design on the center pin. The cheap connectors I picked up do not, for example. But, the higher quality ones do.

    • @dannelson8556
      @dannelson8556 8 ปีที่แล้ว

      +w2aew "Not all BNC connectors have the captive design on the center pin"
      I didn't know that, All the BNC's I've used had captive center pins. I thought the purpose of the captive pin was to relieve the dielectric and center conductor of the insertion load. If the pin is not captive then the dielectric and center conductor take all the compressive force when connecting the BNC.
      Anyhow very nicely done video, thanks.

    When you push the cable with the pin into the main connector body, there should be s slight click as it locates.

      It depends on the design/manufacturer of the connector - some of them click into place, some don't.

    Great educational video. I prefer soldering the the center pin, but you have to be quick, else the polyethylene expands and you won't be able to get it into the connector. I have had trouble with crimped center pins. They are OK initially, but after a few years the connection degrades from oxidation I suspect. I also use heat shrink as you mentioned, allot of bending at the shield crimp ferrule.

    • @alanbrown397
      @alanbrown397 6 ปีที่แล้ว +1

      If you are having trouble with crimps, then you're either using the wrong tool die or the wrong connectors for the cable.
      A _properly_ done crimp has contact pressures exceeding 1000 tons per square inch, resulting in the bond becoming stronger over time as metal ions migrate between cable and pin/ferrule, resulting in a cold weld.
      Soldered connectors have a maximum lifespan of about 30 years (lead solder) and it's much less with lead free solder. These are both due to tin whisker growth (it happens with leaded solder, just not as quickly.

  • @thogevoll
    @thogevoll ปีที่แล้ว +1

    Great video except for one very important thing. You did not mention the crimp die sizes. My crimper has six die sizes and It is supposed to be used for 58, 59 and 174 coax. I think I got the correct dies. I used 0.213" for the collar and and 0.068" for the center pin.
    I approached crimping the center pin a bit differently. I placed the pin in the jaws of the die and closed it enough to hold it in place then inserted the center wire and crimped the pin. It held tight and I didn't have to finagle the wire with the pin on the end into the crimping die.

    • @w2aew
      @w2aew  ปีที่แล้ว

      The center pin typically used a 0.068" die, and the outer ferrule 0.213". But, always best to check the sizes recommended by the connector manufacturer.

  • @smudgerdave1141
    @smudgerdave1141 8 ปีที่แล้ว +8

    Hey Alan - another great video. Just a couple of comments from someone who has done thousands of BNC crimps. Firstly, to get the best result, you need to have the correct crimp tool - not just a good quality one, but the correct one. Secondly, the purpose of the hole in the side of the centre pin is so you can see the end of the centre core. It is not a solder hole and I don't recommend you solder the centre pin. Thirdly, as Axel mentions below, with some manufacturers, the centre pin "clicks" into place. Fourthly, some people tend to double-crimp the shield. This is considered bad practice and is not recommended. Recommended practice is to crimp once hard up against the connector body. This allows the open end to flare - which provides strain relief and catches the coloured boot (if fitted). Which leads me to the last point - you can buy coloured plastic boots to fit over the larger crimp (in lieu of the heatshrink you mention). But again, you need to get the exact right boots for the connector and cable. If you are doing any significant quantity of crimped BNCs, then buy the connectors, boots and crimp tool from the same manufacturer. The manufacturer of choice used to be Greenpar, but they go brought up by Tyco (TE Connectivity) so you need to be careful you get the old Greenpar designs with the Greenpar crimp tool. HTH

      Why do you recommend people not to solder the center pin? Thanks for the tips.

    • @smudgerdave1141
      @smudgerdave1141 8 ปีที่แล้ว +3

      +Robert Calk Jr. - If you have the correct crimp tool for the connector and the cable, there is no need to solder - crimping is quicker. The only reason you might want to solder is if you have the wrong crimp tool or out of specification cable. Professionally, this would be seen as a failure. Also, as mentioned below, you need to be careful with soldering as its easy to use too much solder and have the pin not click into the insulator properly. The BNC connector/cable combination has a characteristic impedance and excess solder may distort the dielectric insulator (affecting the impedance) and finally a solder joint has less flexibility and is more prone to stress fracture than a crimped joint. I concede that these are small points. HTH

      @robertcalkjr.8325 8 ปีที่แล้ว

      +Smudger Dave
      OK, thanks. I'm just a hobbyist and always assumed that soldering was best anytime it's possible. I made my own leads for my DC power supply out of quality wire and crocs because the cheap leads that came with it melted when the power got up to around 4A. After crimping the crocs to the wires, I soldered them also thinking I would get better connections if the solder filled any air gaps within the connection.
      Do you experts think I was wasting my time worrying about soldering them?

    • @smudgerdave1141
      @smudgerdave1141 8 ปีที่แล้ว +2

      +Robert Calk Jr. - No if you are not sure your crimp worked out perfectly then adding solder is good, provided you don't need flexibility at the junction between the wire and the terminal.
      Soldering is one tool in your armoury and is often not the best solution (for some combination of cost, time taken, reliability, quality statistics and capital investment).
      Not only is crimping better than solder, (done properly, natch); Insulation displacement is better; resistance welding (spot welding) is better; ultrasonic welding is better (under certain circumstances) and cage-clamping is better than solder. Spring-clamping is arguably better than solder providing the terminal design is good. The list goes on.
      In fact, soldering can be the cause of problems. Solder exhibits a mechanical phenomenon called "cold flow". If you tin the end of a wire with solder then clamp the tinned end under a screw in a screw terminal, over time the solder will move away from the high-pressure exerted by the point of the screw. After a few months, the screw will be loose and the connection unreliable.

    If you can do it by not using proper tools to strip the wire, depends on how large of a bandwidth you need.
    Larger bandwidth has basically zero tolerance for errors when stripping the wire.

    • @w2aew

    The thing I hate about crimps is that when you don't do them very often you almost have to relearn the process all over again (just like soldering them!). Coincidence seeing your video (great BTW!) as I just needed to put some crimps onto a run of LMR240 and LMR400 and really like the stiff wire trick to measure the length of the inner dielectric; silly me sitting there with a micrometer and trying to eyeball it! DXEngineering has some really nice coax prep tools that nicely strip the outer cover and minimize the chance of nicking the inner conductor. TNX Alan! 73 - Dino KL0S

      As long as you are using the correct die set for the connectors/cable in your application, a quality ratcheting crimper like these will be fine. I am not familiar with Fakra connectors, but if they have a set designed to be crimped, then they should be able to recommend the appropriate die set.

    When I solder the centre pin I first wet the wire with solder, then wet the hole of the centre pin from the back, grab it with some pliers, heat it from the back and slip it on the wire, while pulling the iron away. This way I don't get solder on the outside of the centre pin, because I'm only touching it with the iron form the back.

    Tip for the centre pin is to gently grip it in the tool and then put the centre core in and then crimp.
    As well you get a nice extra boot that you can use instead of the heatshrink, though it is good to slip a small piece of clear adhesive lined heatshrink tube over first, which then is used to hold a strip of paper laser or inkjet printed with a cable identifier. Or use larger cable markers, which slip over before crimping.

    Thanks for crimping the center connector! There are a lot of videos from the CCTV guys on youtube who just leaves it hanging, without any crimping.
    On another note, I was always taught that the center pins without the tiny side-hole should be crimped, and the ones with the tiny side-hole should be soldered to the center conductor of the coax.

    • @w2aew
      @w2aew  8 ปีที่แล้ว

    • @ancelb9590
      @ancelb9590 8 ปีที่แล้ว

      +w2aew I can see how soldering can lead to less loss in the longer term due to oxidation limitation. A proper solder joint with the eutectic dissolving into solution with the copper provides a high integrity bond with maximum contact for best conductance and lowest inductance. Matters of some value in mobile RF/UHF devices.

When measuring to cut the braid I like to add a further 0.5 to 1 millimetre to allow for the loss in the bend of the braid round the inner ferrule depending on the actual design. It may not be much but I believe it makes for a better connection.

    Another great demo as usual. I do have one suggestion. When crimping contacts onto small wires I find it preferable to place the contact in the tool and then insert the wire into the contact. I do this for all connector styles. The position of the contact in the tool is usually quite critical and can be varied enough to make a poor connection. I also want to point out that BNCs are readily available in both 50ohm & 75ohm impedance. I don't know of a way to distinguish between them visually so be careful when buying them because the seller might not know what they are selling. Coax is usually marked with an identifying number and sometimes the impedance so if the connector fits the coax it's likely the correct impedance.

    My problem, it is not RG-58, Where the 6 connectors in DVR, The cable is very small diameter. The end of cable connect to DVR. Also it is 100 ft in length, and coming from the floor from crawl space. .The BNC is already installed in cable, like about 8 connectors on the wire assembly. Problem the cable broke off the connector.

  • @jasongrenier5566
    @jasongrenier5566 3 ปีที่แล้ว

    Why are some connectors rated for 50 ohms, but they fit on a 75 ohm cable? For instance, the Amphenol 31-4321 BNC connector is 50 ohms, but it was made to fit on RG59 cable which is 75 ohms.

    This comment/request might be a little out of scope, to calibrate a Tek SG503 Tek says a special cable is required, Tek part 012-0482-00. This is an extremely expensive 3 foot 50 ohm BNC cable, $200+ on ebay. There's a discussion going on at TekScopes@group.io about the need for this cable and thought this was right up your alley for a video. How do you make a precision application cable in the home workshop? What is this cable doing that another 3 foot 50 ohm terminated cable can't do? I'm a m addicted to collecting Tek 500 series plugins for my home lab and have a SG503 and would love to make one. Thanks and love your videos.

    • @w2aew
      @w2aew  5 ปีที่แล้ว

      I looked up the engineering specs for that cable - doesn't look like anything super special. 012-0482-00 refers to a 36" +/-0.5" long RG-58C/U cable with BNC connectors and strain reliefs. The BNC connectors are to be per MIL-C-39012 spec, which basically applies to most high-quality (reputable manufacturer) connectors, rated to 4GHz, max insertion loss of 0.2dB at 3GHz, VSWR of 1.3:1 max with TFE insulation. Nothing super special, just a 3' 50ohm coax made with quality materials.

  • @joesav37

    Hi everyone - I have been stuck on a cable that doesn't have a single copper pin going down the middle. There are several wires spun together so it has been difficult to crimp a pin on. Does anyone have any advice how to crimp a centerpin onto this cable? Thanks in advance.

  • @physiqueDrummond
    @physiqueDrummond 2 ปีที่แล้ว

    Thanx! From video: outer jacket, 20-25mm; shield length left: 7 mm (≈ connector ferrule length); insulator left: probe with a wire and bend (2m38s); central conductor: with pin over it, pin should touch insulator, cut small bits progressiveley. Voilà! Salutations du Québec!

  • @AlexeiPolkhanov
    @AlexeiPolkhanov 8 ปีที่แล้ว

    I always use rg402/rg405 semi rigid cables just because I can solder them to the cable without crimping. I am unable to get these crimp connectors right 50% of the time for some reason.

  • @ancelb9590

    • @ancelb9590
      @ancelb9590 8 ปีที่แล้ว

      +w2aew Ok, I am getting into the IoT arena and tuning of impedance and antenna matching for optimum range using ESP8226 modules is going to become a focus. I recently got a calibrated HP8753D S parameter VNA and a professional SMA SOL cal kit from KirkBy Microwave. Soon some professional 26.5Ghz cables will arrive and I'd be in a position to explore the area. Perhaps I could contribute to your channel?

  • @adamcumberlege8228
    @adamcumberlege8228 5 ปีที่แล้ว

    Sorry to have to say this, but the procedure is flawed. The CRUCIAL step is the "click" sound when inserting the inner ferrule. It takes a little effort but the difference is another 1.5mm further in. This is the most important step, everything else is fine. Also, do the "finger-nail" test. A man's short finger-nail should be able to touch the inner conductor easily after assembly, the tip should be almost flush with the top annular ring.Lastly, there are 2 styles of inner ferrule, (1) pointed, ie sharp, and (2) bull-nosed, ie rounded. Rounded are better because they present a larger diameter earlier in the insertion process. It would be lovely if you test this and re-do the video as there are so many bad BNC's out there. I work in the aviation and electronics industry and whenever someone complains of poor radio performance this has been the culprit about 90% of the time. Let me know if you check this - ps you have to push the inner connector HARD (and make sure you have a little more slack in the outer braid). Thanks.

  • @ramtek2702
    @ramtek2702 5 ปีที่แล้ว

    As you correctly point out the most important part of a successful outcome is the proper crimping tool. Unfortunately, connector vendors have no idea what size crimper is required for the connectors they want to sell you. They also will lie about what coax fits their connector. Your video mentions nothing about the proper size crimp dies for any of the many BNC connectors nor do you mention a reliable connector vendor. Certainly not ebay.

  • @alanbrown397
    @alanbrown397 6 ปีที่แล้ว

    Soldering is _far_ less reliable than a properly done crimp.
    BTW it's easiest to fit the ferrule (and strain relief) before you go anywhere near the cable with a knife. Decent plugs will have a manufacturer's dimensioning guide either with the pack or online. :)

    I bought a set of crimp BNC connectors and the tool, because I was so frustrated with the compression type, which I believe are better. I have since learned to terminate the compression type. I’m still glad I have both types now. I’ve been doing CCTV work for two years, as of this comment.
