Thanks for the video Stuart, That does seem like a cool build. One of my 2021 HAMGoals was to build a portable 2m yagi for SOTA. I was inspired by the one that Adam (K6ARK) had done, unfortunately that project will roll over to 2022 but you provided some nice ideas. I'm not an ultra lightweight hiker so I have a little flexibility. 73
Very cool! I have both the Arrow and the Elk 2M/440L5 antennas. I was wondering, with the bungee corded elements do you have any problems with erratic SWR? It looks like the small amount of play where they slip together might be a problem? Great video.
I know this is an old post but for the benefit of anybody who might run into this, this is an antenna it's working at RF frequencies, this is not a DC circuit so the connections between elements don't need to be torque down, just being in very close proximity to each other they will capacitively couple. If you've done any RF engineering you'd know that in RF circuits quite often components aren't actually physically even touching they are capacitively or inductively coupled. What this means is that the parts don't need to fit really tightly together in order to get a good electrical connection because you're not really looking for a good electrical connection you're looking for a good RF connection and all a good RF connection requires is capacitive or inductive coupling. Now with that said come on an excessively loose element could generate popping noises on receive and if you're working in full duplex mode you could wind up with duplex noise, but the elements would need to be relatively loose for that to occur..
Love the progression…nice work! 🍻
This is extreme, and I appreciate that.
Great ideas here. I've been trying to figure out a way to make a light, portable/collapsible tape measure antenna, but this looks to be more durable.
Glad it was helpful!

Sounds great Jose! Have fun with it. 73
very well done!
Excellent Stu
Thanks Joe! 73
Terrific video!

I measured the SWR and never had any issues. 73

So whoever makes and sells a carbon fiber boom with shock cord elements is going to make a fortune $$$
I've built one. I just haven't done a video on it. It's pretty compact and lightweight. 73
Thank you for sharing your knowledge. 73. Bret C / AC0AE

ola´. tudo bem? muito bom o projeto. parabéns. PS8JAR QRA-AUGUSTO.
😊👍
Fb man! Hope to catch up with u sota. Cw
See you on the air. 73
Very interesting video, thank you! 73 PA5BAS
