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.

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!

Hi, Great Job! I have a similar project like yours. I see that you shared a link for the antenna. I also like to build one for noaa satellites. Do you have the drawings for the antenna? Thanks

Hi, great work .I am trying to build the 433mhz yagi . So I want to know all about your project . I will be very thankful if you can provide me some information about your project.

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?

Great job! Can I find out what kind of rotary mechanism you use? Where can I buy one?

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

@@sandymal3251 Just now I want to write a comment that it's home brew :-) 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.

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
@RobertKocian 5 лет назад
Hello, distance is 1/4 lambda. I followed instructions by www.qsl.net/sv1bsx/antenna-pol/polarization.html

​@@RobertKocian Thanks. As my understanding, we will build 2 yagis independently (already matching, balun...) then connecting them together?

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?

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 3 года назад
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.

I guess the arduino code isn't enough for you. It's not so simple. But, here you are ... www.kocian.info/blog/download/Rotator_Portable_Arduino.zip :-)
