    Used to do a lot of these with RG-214, it's certainly the kind of work where good tools are critical.

    *Trivia, of sorts:* The "N" stands for Paul Neill, the designer. There's also a smaller "C" connector named for Carl Concelman. So merging the two designs into a small connector gives us a BNC connector, a twist-lock "Bayonet Neill-Concelman", while a TNC is a threaded version.
    Back in the late 1980s while working with early Ethernet networking, I had to install several N connectors on the "trunk" coax. They weren't the crimp style, they had a threaded collar with a hex shape, and the connector body had flat spots 180° apart to allow using an open-end wrench during assembly. Crimping is so much faster and easier, as demonstrated here in the video.

    I had to smile when I saw the little saw for trimming the center conductor 😂
    I did quite a few BNC/RG316 cables lately and that’s completely on the other side of the spectrum 😅

    Another useful and entertaining video. Watching you do this gives me the knowledge AND the confidence to do it. After watching your other videos I’ve gotten pretty good at BNC and PL259’s. But have only tried N connectors a few times. Thanks Alan! de W3AL

    Nice video, very clear step by step. Thank you for pointing out good techniques, avoiding potential issues with too little or too much solder, or being sloppy with it. Taking your time to make sure the connector stays properly seated onto the end of the cable before and during crimping is essential to produce the best physical and electrical attachment.

    I needed precisely one of those male N with LMR600 a few years ago... I've done a lot of RG316 RG58 but for this job i didn't feel quite up to the task, I've ordered it 🤣

    Good way to test if the connector center pin is fully seated after crimping is put your thumb over the end of the connector and press lightly then look at your thumb and it should look like a bullseye with the center pin as the center of the bullseye---N3HTZ

    When doing a lot of these it pays to shell out for the Times Microwave EZ series connectors. No centre pin soldering or crimping required. It connects with spring fingers in the connector body.

    I'm using this video since it's your latest to date thinking there's might be a better chance that you would get to see it. Could you please do a video on attenuators. Perhaps the different resistor circuits, measuring them with dB, and also including how to use them in a project a person may be doing. I am currently making a pulse/function generator out of TTL devices just for the mere fun of it. It would be nice to include an attenuator in the project. I concur with most of your commenters that you are an excellent teacher. Many thanks for considering this.

      @@w2aew Thank You. I went ahead and downloaded it into my resources folder. Quite a treasure chest full of information. A quick question. On your video No138 "How to measure output impedance" you showed us a function generator that you had built many moons ago. I understand the output AC and DC coupling with a capacitor in series with the DC side and bypassed on AC. Your "coupling" control has +DC and -DC. This has thrown me a curve ball with a swing and a miss! The "invert" circuit has me doing some mental gymnastics as well. Needless to say, I'm very much a tyro novice! Do you still have the schematics you used to put this gem together?

    • @w2aew
      @w2aew  Рік тому

      @@scottmorgan5370 The +DC and -DC allow me to add a positive or negative DC offset to the output. Invert turns the waveform upside-down. Doesn't matter for waveforms like sine waves, etc., but does have an effect on asymmetric waveforms.

    Looks nice! I saw some old videos where they used thermal type wire strippers on stranded electrical wire that melted the insulation without nicking the wire. I wonder if such a tool could be fabricated and implemented for coax use? I find if I bend the cable in my hands slightly that it cuts through the outer jacket easier as there's a little tension on it. I like your "work backwards" idea here. Thanks for showing and 73's.

    Very nicely done. But I noticed that your stripping did not match the dimensions on the figure one to one. Either that figure was not to scale, or dimensions that work well are not that precise.

    w2aew there is a mass confusion over the difference between bead, choke and inductor. They all have inductance but are not the same thing. I still do not understand the difference between these.

    Times Microwave CST-600 prep tool will permit you to do this virtually blindfolded, you won't run the risk of cutting your finger off, and you'll get a better job, end of story. Don't get me wrong The box cutters and utility knives have their place in a pinch but why do it the hard way?

    • @w2aew

      Proper coax prep tools are definitely the way to go if you have a lot of terminations to make. However, those excellent Times Microwave tools are an expensive proposition for folks that only need to do a small handful of connections.
