Transformer Zatsarinina
Single turn inductor ( split copper tube ) inside ferrite :
Thats amazing.
Kind of a trick
The copper tube with a slit represents one turn of a transformer
The nail represents one turn of a transformer
The ferrite is the core
1 : 1 transformer
Hi All,
The way its made with the 'windings' as they are the nail appears to be at 90 degrees to the slotted copper, assuming the feed cables are next to the slot but as they appear at each end it is probably transformer action as the length of the tube is far greater than the slotted ring formed. Theres not much looking at it from a UHF point re. long wires and ferrite being used.
