Ham Radio Satellites with Two Arrow Antennas and Circular Polarization?
HTML-код
- Опубликовано: 5 авг 2024
- My new "mini-array" is born, using two Arrow antennas phased together. I'm using switches that allow changing polarity between vertical, horizontal, left-hand and right-hand circular polarization. This setup is an experiment to test if switchable polarization will allow these little antennas to outperform a set of higher gain fixed antennas in real amateur satellite use. Either way this will be a lot easier to transport to field day! I've wanted to try this for a few years and am excited to share my project with the community.
Part 2 to follow with on-air testing once I finish the control cables and get the antennas mounted.

I LITERALLY just bought one of the Arrow antennas to use for Field Day! 🙂 - And like you, I've beem running fixed polarization (vertical in my case) for satellite operation, with the resultant fading issues you mentioned, so I'm VERY interested in seeing how your project turns out, I may do the same!

can't wait for part 2!
Great project and thanks for sharing and taking us along on your journey
Brilliant and so straightforward.
Subbed and waiting for part 2.
Thank you for sharing and that is just awesome what you built. I look forward to your testing.
Thank you for the encouragement!
Hello Alex,
Thanks for sharing.
Amazing project Alex!
ooooh... those nice switch kit seem awesome ! great finding !!
Awesome video and build looking forward the 2nd installment!
Thanks, part 2 is out now!
Excellent work!
Glad to find your channel also!!
This is EXACTLY what I am working on! Thank you! You saved me a lot of time and money :-Dn Hope to see you on the satellites! K9EZ
Great Video. Thank you very much!
Great project. Excellent video! Very well explained. Congrats! 73
Thanks Pablo, your encouragement is greatly appreciated.
Beautiful.
Excellent! 👏👏👏👏
Very nice project. I'll follow it! 73
Hello congratulations about your new contraction so we waiting for next video with results!

Fantastic!
I can't wait for the satellite hunt!. 73DX!
Congratulations on this very interesting project. I'm looking forward to the second part. 😀 vy 73 de Andreas, dl5lc
Oh, now I see there is another video on your channel...
Cool!
Very glad I found your channel. Great video, very impressive hope to make contact with you on the satellites. I've been thinking about installing an HF beam under my antennas like the 6 meter one you have and was wondering if they would interfere with each other. I have subscribed and looking forward to more videos.
Thanks for the kind note, glad you liked the video. The antennas probably do interfere with each other, but there are a lot of compromises I've accepted in this setup. I'm sure there are calculations or simulations you can use to avoid any interference if you're very concerned. In my case it hasn't stopped me from reaching VUCC on 6m and satellite.
it will work that is what I have for LEO's WB5MZO
Is part 2 out there 🤔
Great video! Lots of great info.. Do you have a write up on the project? Wondering if you jotted down a bill of materials and such? I have the “Alaskan” Arrow and was thinking of buying a second and doing the mods to make one for UHF & the other for VHF, like yours. :)
Nice one Alex, I’ll be watching this with much interest as I’m planning on a portable EME system to get away from all the QRM at my home QTH. I wonder if you’ve considered scaling this up at some point for EME/p cheers and 73, Richard. G0NAD
I'm glad you asked, I've been slowly assembling an EME station for a couple years that will be portable and mounted to a trailer. I plan to start with a 6' dish on the 23cm band. But I'm also considering a 2m or 70cm build. I have lots of ideas but never enough time! I've been blown away with the amount of interest in this project though and will be diligent about making RUclips videos on all my future projects.
Very nice! I just received my antenna rotator from Sarctrac in Australia. It’s a wireless rotator that does azimuth and elevation. I will be using a dual band elk log periodic beam antenna. I am also waiting for a wireless controller and a stepper motor that will enable me to adjust for horizontal and vertical polarization. I will post a video when I get this project together.
Sounds fancy, have fun!
Very cool I am dreaming of something like that in my futur., Question I have a similar set up but with one 2m arrow vertical and one 70cm amazon brand yagi horizontal. I noticed your gamma match are upwards and not downwards. I have mine mounted downward is that a flaw in my install?? Thanks
Need to explain about the phasing of the ant
Great video .i wish I had friends that gave away 2 x£350 worth of preamps.
I've found that the ham radio community can be very generous when they see someone who is passionate about the hobby and wanting to try new things. Making these videos is one way I've tried to give a bit back. Glad you enjoyed watching!
Yes, all other things being identical, bigger is always better.
Of course, but what about when other things are not identical? Spoiler alert: bigger is still better. Part 3 coming soon with my conclusions.
👀👀👍🏻✌🏻🇨🇦
The phasing kits look good but using BNC plugs….uggg.
Nice setup. Not for me, too pricey.
I agree it is an expensive setup which probably doesn't make sense if I was buying everything new. I've been very fortunate to know local hams who enjoy my antics, and they have generously donated some of the high value parts like the G-5400 rotor and preamps. Also this setup is really just an experiment and I wouldn't really suggest others copy it. I've been distracted with other projects recently and behind schedule for posting an update but I will address all of this in the future. Thanks for watching!

Nice set up. I have just started homebrewing antennas, now into second step of 7 el VHF Yagi, yet to complete it (ruclips.net/video/N0n6RE3gwOA/видео.html). Subscribed to your channel so that I can come back and look again when my homebrewing skills improve enough to go for arrays!
Showoff 😂
да не нужны две поляризации.через спутники и так связь 100% зачем такие сложности?
