This is my 1:1 Choke Balun Build. I may use this on an upcoming new antenna project e.g. doublet, dipole or fan-dipole. I can also add and adapt this design to make a 4:1 balun for say a loop or off-centre fed dipole.
In researching this build I can recommend the following two sources of information:
G3TXQ (SK) Baluns: karinya.net/g3txq/baluns and chokes: karinya.net/g3txq/chokes
TRX Lab/Bench: youtube.com/watch?v=kMlKfHHR8FY (Part 1 of a 3 part series - watch them all!)
I sourced my 2x1m (red & black) wire lengths here in the UK at: hobbyrc.co.uk/18-awg-flexible-silicone-wire-black-red-1m-2
This is one of many amateur/ham radio related videos on my channel. Please feel free to browse 👀, like 👍🏻 and subscribe 🔔, remembering to hit the bell so you’re notified of new videos as soon as they're published and you don't miss out.
Thanks.
