PREVIEW: RF Choke Calculator & Design Guide - Understanding the Physics Behind Your Coax Balun

PREVIEW of our upcoming RF Choke Calculator project - a comprehensive design tool specifically for RG-213 coax chokes on 4" formers.
Earlier videos to watch:
• Why Your Choke Balun M...
• Baluns - Why so import...
• FREE - Latest LFA Yagi...
This calculator will cover:
Frequency range 1.8MHz to 60MHz
Turn calculations per band
Spacing requirements
Power handling for SSB/CW/Digital modes
Temperature derating factors
Installation requirements
Learn why RF chokes become less effective at VHF frequencies through understanding:
Skin Effect - why current flows in an increasingly thin layer
Centrifugal Effect - how RF concentrates on coil outer edges
Proximity Effect - turn-to-turn interactions
Combined effects leading to thermal issues
Real-world power limitations
Key Features:
Band-by-band specifications
Minimum spacing from metallic objects
Temperature compensation
Digital mode derating
Critical installation guidelines
Full construction parameters
Coming Soon:
Additional calculators for other coax types including RG-142, RG-174
VHF/UHF ferrite solutions
Installation guides
Testing procedures
Troubleshooting guides
Subscribe for updates on this project's release and future calculator tools for ham radio applications.
Note: This calculator is specifically optimized for RG-213 coax. Different coax types require different parameters and will be covered in future releases.

Thank you, my presentation was not so good this time, I was in a rush as I had a plane to catch that day!

Subscribed and joined, can't wait for the rest, 73.

[@hamradioguys]

Thank you very much, lots being prepared right now, stay tuned!

Like, subscribe and sent it to my radioactive friends! Justin, next please!

[@hamradioguys]

Thanks so much, really appreciated

Why not broadband choques using ferrite instead of just a narriw band choke using the coax over a 4 inch form?
Can we use several coax chokes in series instead of a single one?
I was imagining feeding the antenna with the smaller number of turns choke close to the feeding point and another with larger number of turns about one foot apart.
What about using half inch Superflex foam insulated coax instead of 10mm polyethylene insulated rg213?
