    Copper foil tape will do the same for bandwidth. Just wrap the pvc with it, solder on some jacks to make it easy to disassemble. But using what you got is practical and simple stupid. Always liked the idea of flipping the antenna 90 degrees but never had an elevation rotor to play with. I have a scorpion 8 element still in the box I want to try it with as the last one used a relay and I wasn't happy with it.

    I like the PVC hanger method. Lower Weight is important as is rigidity -- could do something similar with 1/4 inch schedule 80 etc. Playing around with antennas is fun.

    Question:
    Why not use a tape measure? Just punch a few holes in it with a screw driver and screw it onto the PVC? The tape measure has a natural contour due to it's non-flat shape that would fit right onto the PVC? I can see some advantage of the ladder line for the driven element -- you could feed it as a folded dipole ! No hairpin required !

    I spent a few days pursuing setting the driven element up as a folded dipole using a 'trombone' coax match method. It was fiddly and hard to get working well, plus it was bulky with the extra coax involved. I chose to go with the hairpin approach to keep things lighter. And it was easier to get it working reliably.

    Nice video, but why not put the elements in the PVC pipe. You can fold the ladder-line to make it fit.

    Simple and seemingly effective. Nice job!

    I really enjoyed watching your video. Nicely done. I saw the comment about using copper foil and I had that thought as well. However, we all have window line laying around and it is also easier to cut and tune besides being cheaper.
