Hello SatNOGS team,

Its great to connect with you here. I would like to startup with building my own ground station and connect it to SatNOGS network. Please assist further how and from where to manage to arrange hardware parts kit for antennas and its rotor assembly. Thank you for your valuable support on this in advance.

welcome friend!

Hello @bali Thank you for your prompt feedback reply to my post. I really appreciated it.

I reviewed your recommended tutorial link and found that its more about the software side related setup, which is good for the later network configuration setup. What actually i am looking for the antenna and its rotator hardware assembly related parts, I am wondering to know where to manage to arrange these parts for an antenna assembling process? Does SatNOGS sell-off these outdoor antenna assembly parts to build by its users? Thanking you.

what i know they create the kit, ussualy can be found at big amateur events but not rotator.

Hello @bali thanks for sharing the other users posts to help with antenna and rotator harware assembly process. I really appreciate your support on this. But I found that its hard to manage to arrange parts locally and build such kind of SatNOGS v3.1 rotator setup. I think its better to look for a third party low cost antenna rotator. Any further suggustion from you on this will be appreciated. Thanks.

Hi, welcome!

Pretty much @bali already cover it all. And for a starter I highly recommend building simple one with and Omni antenna first like a Turnstile or QFH.

There are much more satellites on UHF band than on VHF, so you may consider that. My first station #3852 has a “dual band” QFH in which its a VHF QFH but has a resonant frequency on UHF too, but its less effiecient than purpose built UHF antenna.

My second one #4204 which I use mostly for experimental use has a SatNogs Rotator, so it can auto track the satellite with every observation. It was disconnected at the moment as I’m on the process of upgrading the antenna and amplifier system. The rotator itself I built mostly from scrap extruded alumunium and spare parts I have laying around with the only new parts is the 3D printed one, so I calculate it cost me less than $100 to make.The system itself wasn’t mature though as I am still learning to connect the rotator to the SatNogs Pi properly though I am using the rotator on almost day to day basis for FM (and for the first time linear satellites just a few days ago).

So back to the question, there are many option for rotator with the most common is using Yaesu G5500 which is pretty expensive. Here’s the list but there are plenty more options like I found with my friend from China who has a PTZ CCTV mount converted to antenna rotator (though I found out its pretty common).

And uh, also please be aware that not every rotator can support/connect SatNogs from the go and you may be on your own when doing troubleshooting :slightly_smiling_face:

genius!

Hi @alpha_adhito thank you very much for your suggestion and explanation on antenna and its rotator related parts for SatNogs first time ground station setup. I really appreciate it.

So i decided to try with simple one first like Turnstile or QFH to test with signal recieving and would think to antenna rotator build for later. Could you please further assist me from where can I get thisTurnstile or QFH antenna? Thanking you :slightly_smiling_face:

Sure, that’s exactly what I did. I did the rotator mostly for my hobbies tinkering with stuff, thats my I named it as experimental station :grinning_face:

Here’s some of the list of omni antenna that I have built, but I am sure there are much more options out there.

Dual band QFH antenna

3D printed turnstile antenna

QFH antenna calculator

Hope that helps
