NOAA Cross Yagi & Antenna Rotator

[@lordgarak]

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.

[@uranshrestha8666]

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

[@uranshrestha8666]

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.

[@Paturnus1]

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

[@RobertKocian]

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?

[@Paturnus1]

@@RobertKocian This sounds good. I need a push in the right direction. ;-)

[@RobertKocian]

@@Paturnus1 It's harder than I expected. Tomorrow evening will be continue. So far, only assembly drawing of rotator.

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

[@bigboy061293]

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

[@RobertKocian]

@@bigboy061293 Exactly ;-)

[@bigboy061293]

@@RobertKocian thank you so much!

[@amiteshwarmann7556]

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!

[@sandymal3251]

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

[@sandymal3251]

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

[@RobertKocian]

@@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.

[@forestroby]

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

[@honzak415]

Super práce, taky bych chtěl takovou anténu doma, na kolik vás to vyšlo?

[@Poligl0t]

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?

[@sandymal3251]

А где приобретали сам механизм?

[@mcshedmamag8037]

How much your rotator sir

[@loumercado5565]

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]

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.

[@Unkl-T]

WOW! Now that, is bad ASS!

[@ssjeon7490]

Perfect!

[@Geekchess]

Very cool!

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 :-)

Super!!!
