    I have a pole and rybakov antenna. The antenna is made from washing line from asda £1.50 for 20 m then a 4 to 1 unun on the base got Australia, Brazil and Uruguay from the west coast of Scotland on 10m and 20m with 80 Watts. Its really quick to put up and take down . The most expensive thing is the pole

      @@Maartenkarperfreak Thank you! If you can I would recommend a fiberglass pole since carbon is conductive, but as you see it works in a pinch! Good luck with your antenna project!

    Just to let you know, the poles are measured for length before they are cut. You lose length because of the friction fit parts. If you took it apart and lined everything up end to end, it will be close to the advertised length.

      @@btaylor1948 It might be a bit difficult to see in the video, but I leaned the mast against the root of a piece of driftwood that was lying there, then I used a couple of tension straps so that it wouldn't slip.
      Luckily there was no wind. Otherwise, it probably wouldn't have worked.
      After the video, I made s better system where I use a 20cm piece of pvc pipe attached to a 50cm stomp of rebar. Nothing fancy, but it works great! 73 my friend!

    Interesting video and quite a nice spot you were working from, thanks for the fine entertainment! You got a new subscriber. I happen to have two of these poles, most likely the same brand as yours because I distinctively recognized the end cap with the fancy design! I have one 10m and one 13m model, neither of these are of their advertised lengths just like yours. A good 1.5m shorter than this, even counting the super-thin top segment that's hardly usable for anything.
    The 10m one actually is even shorter now, because its lower segment broke in a not so strong gust of wind 😆. They're kind of fragile, and I really don't think that they're actually made of carbon, are they? More likely good old fiberglass.
    I often stick a Rybakov antenna to these too. The same as yours, which I bought ready-made as the M0CVO "Magitenna". It's easy to deploy, easier than the 20m EFHW I also use. It works okay, not always great though. My assumption is that its efficiency highly depends on the kind of soil below, its conductivity. Do you share this observation?
    Keep up the nice POTA videos, I'll be watching from now on.

      Thanks for the kind words! Yes, it may be fiberglass, but it says carbon. I don't really know. I'm thinking I should do a comparison video of this rod and a DX commander rod to see if there is any noticeable difference between them.

    • @F4LDT-Alain
      @F4LDT-Alain 2 місяці тому +1

      Thanks for replying! I also have a 12m Spiderbeam and the thing is so heavy I can't bring it up by myself when extended if there's the slightest wind. Also it's too wide at the base to plug it inside any umbrella stand ground socket I could find. So I don't use it much really. These fishing poles are much easier to use but alas quite fragile and too flexible...
      Judging from what I saw when my 10m pole broke, I really can't imagine this is carbon. It really looked like fiberglass. Carbon ought to be conductive, right? So I'll check with my multimeter...

    Carbon fiber is conductive. You are not supposed to use these for antenna support. Sure it makes the swr look good because it is absorbing so much power. Use fiberglass instead. Yes I know you made some QSOs.

      ​ I really can't tell how much it's absorbing, but try pulling the antenna wire away from the mast and observe the swr. If there is a change then you know the mast is conductive. I know one guy who actually used one of those masks as an antenna.

      As I wrote in another comment, I have a pole from the same brand and I highly doubt it's carbon. It definitely looks like it's fiberglass. Plus they'd be more expensive...

  • @StreakyP

    The problem with carbon poles is you never know how conductive they are going to be & how it might affect the antenna but there is an easy test..... Build the antenna using a fibreglass pole & measure the swr. Then bring the carbon pole next to it & see if the swr changes or rssi drops. No change is good, change is bad... Even an IMPROVEMENT in swr can be bad as that can signify that the carbon is lossy and absorbing energy.
    There is of course the other way of testing in building it with carbon then putting a kW into it and checking for flames!.
    There is good carbon and bad carbon and trying to tell the difference isn't always easy.
