T200-2 Toroid Core Micrometal Powdered Iron

Balun/Unun for the 40, 30, 20, 17 and 15m bands

What can I write about this coil??? Hmmmmm. It was a good coil, no it was a great coil. Its beefy makeup and polished appearance inspired confidence in others. So good was its pleasant demeanor it did not balk in the least when surrounded by copper colored associates and allowed the entanglements of it affairs with no complaints. When asked about his pleasant disposition he simply said, "I'll match anyone, anytime and anywhere."

I purchased this to build a 4:1 unun/impedance transformer for a portable multiband vertical HF antenna. It works as expected. This powered iron toroid would work equally well as a replacement for the T106-2 in the ever-popular 9:1 unun design published by EARCHI, enabling the device to handle higher input power. I appreciate that the item was packaged in a *labeled* ziplock bag, considering how easy it is to keep track of toroid mixes once they're in your parts bin (I typically label them with silver Sharpie after unpacking).

great stuff

What can you say, its a toroid core. It wasn't the one I really wanted. However, I realize it's the one I actually needed. It's a good looking product. I would buy another one.

Excellent quality. Perfect for the 9:1 UN-UN project...

In an an electrical coil this product works very well.

Of course I haven't finished the project yet, so I really don't know if it works.
