More informations
These toroids are particulary suitable for high power or for big size chokes.
Here follows an example of power HF - VHF transformer.

Jumper small pipes made of copper or brass which is the 12.5 Ω impedance side |
 |
Typical application as transformer for HF input or output |  |
Mounting example |

P.C.B. to keep togheter the ferrites |
There are also available silver plated unipolar wires with teflon insulation useful to build inductances and transformers on toroids, see dedicated section.
See the below PDF for an interesting example of construction of HF power transformer.
