    I think I did figure it out now correct me if I'm wrong ;-) each element has a leg of 6.75" and 5.85" so in centimeters that is 17.145 cm and 14.859 cm?

    Alex,

    Will the Turnstile design work with a U.FL connector on the coax feeder? I want to use a Turnstile with the SubMicroLRS receiver.

    Thanks,

    Paul

    As for the units I make professionally, they are balanced a multitude of different ways. Some have ferrites on the cables, others simply use the proper length of cable to keep it from resonating.

    Hi Alex,

    Thanks for sharing this great antenna design! Can you please advise, what is the optimal feed cable length? Or perhaps several lengths: a shorter, a medium and a longer one?

    Regards
