    Nice design. Definitely lots of food for thought as I design my antenna rotator and antennas. I really like the spring clips on the directors/reflectors. The feed point blocks are nice too.

    I am also excited to learn about the tracking mechanism you have built.

    Great Job! I'm also trying to get my Yagi Antenna to rotate. Can you share what motors you used and how you went about? Thanks!

    Do you have plans available for the az/El rotor and the antenna?

      Yes I have. But there is a terrible mess in it. In the evening I will try to purge it. Then will be download link in video description. Can it be?

    Интересно! Тоже собирал такой ротор)) Дольше всего возился с драйвером под orbitron, так как не являюсь программистом. Дорабатывал стандартный, написанный на delphi... Столкнулся с тем, что антенна движется неравномерно, как будто координаты в стандартном драйвере обновляются нерегулярно. Какой драйвер используете вы?

      I apologize for the question. As I understand It, this is a homemade device. At first I didn't see the link to the rotator drawings

      But not quite. I had the parts made in a locksmith's workshop. The documentation in the description is mine and is freely available of course. Parts are dificculty to made at home without machines.

    Great Job!! I'm also trying to build a 2 meter Cross Yagi. I'm also looking to build a 70cm yagi. Would it be possible for you to email me your plans. Thanks in advance. Lou.

    • @RobertKocian
      @RobertKocian  4 ปีที่แล้ว

      Hello and thank you. Plans are available just as a 3D model. I didn't make the drawings. Dimensions are according to the K7MEM yagi calculator www.k7mem.com/Ant_Yagi_VHF.html If you are interested in a 3D model, let me know. I'll send stp.

    Hi, I am going to build the cross yagis for UHF and VHF, can you show me how can I determine the distance between vertical elements and horizontal elements? Thanks.

    • @RobertKocian

      Hello, distance is 1/4 lambda. I followed instructions by www.qsl.net/sv1bsx/antenna-pol/polarization.html
