Centerpiece for dipole antenna with symmetrical feed
by DB3JHF, published
This is a centerpiece to build an dipol with symetrical feed line @ 450 Ohms (like CQ 553 flex wire).
I recommend to use the new version (NG) with the improved and strengthened relief. It is still designed for the CQ 553 flex wire but may work with other types too (reports welcomed).
Print both pieces and if neccessary widen the holes for the pull relief by using a 3mm drill. We haven't tested this thing under hard "fieldday" conditions yet. So any feedback, comments and tips for improvement are welcome!
2nd Version (NG):
I made a new version which should do better. It is designed using the CQ553flex wire as feed. THe pull relief wil be done by putting one hole of the wire into the holder, then just fix it with the relief piece.
