On top of a mountain in south Salt Lake City, Utah there are many antennas.

What are these curly ones?

Looks like a vertical array of circular polarized antennas, each half element as half turnstile and half traveling wave used for the circular phasing.

  • Circularly polarized, yes. I didn't think about that. But what do you mean about the traveling wave part? – Mike Waters Aug 19 '21 at 21:50

    Traveling wave may be the wrong term. But I wasn't sure what to call a widely spaced (non-coax) phasing delay line that might be part of each antenna element. – hotpaw2 Aug 19 '21 at 23:49
