    Oh my God, being a ham in Brazil is very complicated.

    I decided two years ago to drop the mic and pick up the brass. Happy I did, so yeah. Get back into CW. It’s awesome. I do mostly QRP as well now when I decided I would drop the mic. Even though I am still QRO capable I enjoy QRP just as much. Glad you did this vid as I am a fan of your channel. Spider Beam 60ft. pole is gonna find a new home in my back yard.

    Very good! A tip I can pass on after years of keeping a 10m pole up in frequent hurricane-force winds is to take your stay anchor points sufficiently far away that the angle with the pole is as gentle as possible. That way, the stress load during wind puts more of the strain in the horizontal plane, and less in the vertical. With steep guys, the vertical load tries to pull those sections downwards. Elevating the stay anchor points helps in this regard.

    I have one supported by two short pieces of 3" drain pipe attached to the ladder on the back of my motorhome parked alongside my house; have a 43' vertical wire supported by it and a few radials, 4:1 UNUN at the base; works great. Collapse it when I want to move the motorhome and it goes with me..

    Cool ideal how secure the bottom. I just set up the TN07 antenna in my yard for testing. Plan on using the TN07 for camping.

    Good video, thanks!

    This year at the Hamvention in Xenia that big Spiderbeam pole caught my attention too.

    My imagined primary application would be for 160m, with a similar radiator wire run up with the pole, but with addition of top loading, either by symmetrical wires extending / shallow sloping out as far as possible from each side to roughly form a Marconi T; or with multiple wires at sharper inverted V angles (similar to the guy lines) forming a more classic Top Hat. This ought to also improve its operation on 630m.

    IOW, sort of a more symmetrical vertical variation of the classic inverted L style "Battle Creek Special" often used on DX'peds.

    Do you think some top loading like that could be safely added with really light gauge wire, or are the top sections just too flimsy?
