    Mine has been up since Dec. 2018 . I have had to replace the wire on the so239 connector . Restring the shock cord once . Other than that it has done me a great job

    I wouldn't bother if it took that long to set up, but it doesn't. If I went really slow it would take me 20 minutes to set mine up. I suspect there was something else wrong. It is certainly fast to put up the wire as well, I have a 40-10m efhw that works great as a sloper from my 12m Spiderbeam pole.

    I just received mine after listening to many of Callum's YouTubes, and hearing this review. I intend to leave mine up permanently. We shall see:)
    Painted my guy wires bright yellow. May hurt the life of the ropes--we shall see, but they are visible:).

    I think age and club mentality had a lot to do with it! Some videos online seem to show inter-element interaction and hence matching instability to a degree, which you can only really expect, but may not necessarily be a 'problem'.

    On your suphogh,orclov="AB0R, post: 5909341, member: 938203"]I wouldn't bother if it took that long to set up, but it doesn't. If I went really slow it would take me 20 minutes to set mine up.

    On your sloper, to you put the transformer on the high end or the low end?

    Low end. You COULD add a counterpoise or even a ground rod etc, but it's not needed for portable use like this IMO.

    I see. That could have been a thing. Calum now gives pretty specific recommendations for element placement. I just put them where he said and no problems here.

    That is how I use mine, but I have seen others setup the other way.

    Without being remotely QRZ.com-esque, when you say "no problems", have you looked at how the matching turns out with an analyser? And have you looked at any instability introduced by wind due to element interactions? There's at least one video showing poor matching at 12 and 10m. Yes, you can 'ATU' them out, but that's not really very good. You can do that with any not-very-good wire.
