1:1 Balun Air Choke Tube

1:1 balun air choke I'm using on a homebrew 10m center fed dipole. Was trying to eliminate unwanted RF noise. The enclosure is not part of the model, that's an excellent dipole center feed box from LY3SP found here https://www.thingiverse.com/thing:2918893 Please note: it does not fit inside that enclosure without modification. Used 18AWG magnet wire for the winding. The choke is based on a design by KG0ZZ. You can find his how-to on YouTube titled: "1:1 Balun for HF Dipole Antennas". The improvement is having grooves for the wire to seat into, instead of struggling with wire on a PVC pipe. This is a work in progress. Based on how this performs, and it's power rating, I'll eventually be modeling a full center fed dipole enclosure for it.
