Ham Radio Satellites with Two Arrow Antennas and Circular Polarization?

Ғылым және технология

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! 73, Tom WA1LBK

    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.

    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.

    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 KZread videos on all my future projects.

    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!
