I’m a mechanical engineering student right now. I’m in my first circuits class and we are learning about AC. This is so cool. Thank you for inspiring me to get into amateur radio! I learned so much watching this and the previous 3 videos.
Oh dude be prepared - AC in Circuits 1 can be pretty rough because they teach you all the time-domain transient stuff. But don't worry! In Circuits 2 they make AC make a lot more sense using the frequency domain! Idk if they require Electromagnetics in Mech-E curriculums, but if you like RF stuff, absolutely take an electromagnetics course if you get the chance. It's all about EM fields like this! Also, if AC gives you any trouble, Check out Electroboom's "Electroboom 101" video on it. It makes the main concepts very clear and ties in a lot of common applications! (note - I'm a Bioengineer with a minor in electrical engineering by schooling. But I work as a tech doing a lot of power electronics stuff now- Mainly testing commercial LED drivers and light boards, and designing some of the test equipment) Best of luck in your circuits course! I hope it's interesting for you and you get a lot from it!

Hi, I was just tuning through youtube and your antenna series I found very interesting. I am a little too old to be taking up Amateur Radio again. My first licence was from where I was in Scotland and was GM3OGJ, first licenced in 1960. Good luck with the antenna series. 73s
FWIW: I live in North Carolina now, but I was born & raised in St. Pete. I also lived in Dade County for about 7 years. Flip-flops are DEFINITELY mandatory. I _still_ wear them here in NC as long as weather permits.
Thank you for the education. Just acquired my tech license, studying for a general class certification. Love to fabricate and plan to build my antennae.
Great presentation, Derek. I've read a bit about the Moxon, but didn't appreciate nor grasp its directional gain over a 2-element Yagi. 73 de N6BVZ/4 (north Georgia) Wil.
Nice I’m an EE but RF has always been black magic. On directional antennas. I like WWII technology stuff Could you do a video on the Huffduff project? Came out of UK They put the systems on ships to instantly get a bearing on a submarines transmission. With shore Huffduffs and ship huffduffs they could cross bearings to get a location. But, no sweeping of the antenna to find the highest signal strength. I’m guessing two antennas mounted 90 degrees to each other with electronics to do the best angle. I’ve never seen anyone dig into the antenna and RF physics. Thanks again for your work.
James, If you like reading, I suggest "the easy way ham books". Great study guide that teaches you the correct answers to your ham exam. In two weeks you'll be ready to sit and pass whichever class exam you choose to take, except for the extra class license. That will take a little bit more time 😉 Good luck, and don't hesitate! We are around the height of this solar cycle, and you will be able to make the best of a technicians license talking on the 10 meter band. Best wishes!
Hi Derek. I just ran across this video while searching on diy anrenna projects. I've been interested in the moxon for a while now and since it seems to keep showing up in my searches, it may be a sign it look further into them. Also, I will be looking into your element14 community. It sounds like something i would find interesting. How can i find more information on your moxon antenna such as more information on the fiberglass poles and where i might find them. 73 de Joe KB9RCR

Good to see the final result of the theory 👍
Great job with the video Derek 👍

That video is so cool and interesting! Why only 16K views? Super underrated. Congrats on your content.
nice antenna! im looking forward doing my license this or next year in germany 73
Glad to see it’s all come together!
What was the actual SWR reading on the antenna. I like the gain you get and the directionality of this antenna.
I need ur help...i am working on a project called damage detection of road pavement using piezo sensors....can u help me on that topic

Could you do a video on the Huffduff project?

Thanks again for your work.
Out of curiosity, how did the theoretical SWR match the real-world SWR?
Did you use the same antenna to both transmit and receive?
This was great. What is the best way to study and then take the test for my Technician license?

I think the signal reflects not refrect the signal , refraction will let the signal penetrate through the ionosphere , right ??
Thank you for explaining so well. God bless you!

Thank You for sharing 👍👌
FL to QC on 28?! lovely!
p.s. Moxon is a new one for me. thanks!

Great vid. I've been wanting to play with a 10m moxon for years. Maybe I'll finally do it now! 😂
7:47 the finger tap to get busy 😂
Good contact. I think I have worked that guy on 20 meter.
Nice work Derek, thanks for sharing! 73 - Dino KLØS
I love your engineering approach to HAM radio. There is a lot of "just do this, and it'll work". Yeah, but WHY!?!?!
This is super good
Yesterday i catch connection with South America, thanks to Doom
👍👍
