- I picked up a Common Mode Current Choke Test Rig from Halibut Electronics (electronics.ha...) during Hamvention 2023. It is about time I put this together.

Well done Carols. 1) Love the music 2) thank you for the shout 3) I need one of these contraptions
Credit where credit is due dude. You know how to make that NanoVNA dance like no other. Hit Smitty up, $59+Shipping and you can get your very own kit. :)
@@LifeAtTerminalVelocity I’ll ask if I can get the “bro price”
who da Honolulu is Carol, Ape? (a Song from Smokie in the late 1970's may be...?) czcams.com/video/tRvQNlIfKUQ/video.html 😎👍
Awesome kit!! Thanks for sharing! 73!
Thanks for watching! It is a neat kit!
Good Job Carlos, tnx for sharing this with us. I shared it on with my Facebookers. Happy weekend /& 73 de Uncle Günter 💯👍🙋♂
Danke Onkel Günter!
Great video, I have one of those kits I have been meaning to build for about 6 months too!
Absolutely worth the time to build it. Have a blast!
Very nice! One more thing I need to buy. Thanks Carlos!
You know me Jim, always willing to spend your money!
thank you
You're welcome.
Good video and love your energy!
Glad you enjoyed! Thanks for watching.
To be fair to ABR (who make great cables, BTW). That choke you have with the 5 beads, is probably optimized for VHF and UHF. Parasitic capacitance is a much bigger problem at higher frequencies, so keeping your choke linear and not looping the cable, makes it perform much better at higher frequencies.
I wondered why the first big choke did not perform as well at the higher frequencies.
Yep. Choking at HF has many more options than VHF/UHF. I’m working on a product now that needs a CMCC at VHF/UHF, so I’m learning ALL ABOUT this. :-)
I mean even if it is -20dB of choking with 5 ferrites it is still a lot more than I would get without them. I think that their product clearly works based on what the nanoVNA shows.
@@LifeAtTerminalVelocity Exactly. Some choking is WAY BETTER than no choking.
