For my antennas.
I used these to make baluns for my ham radio antennas. They are just as they should be. No issues.

works great - packaging could be better
Works great, but not packaged really well for shipping. They are somewhat brittle. I ordered one of these along with all the other part I needed to build a 49:1 unun for an end-fed half-wave antenna for amateur radio. Unfortunately it was all stuffed into one of Amazon's paper envelopes, which resulted in one casualty - this toroid, which was literally snapped in half, because they put it in a bubble wrap and then into a plastic bag. Amazon gladly setup a return and replacement, but would take a week to deliver the replacement, which was a disappointment to say the least. This motivated me to place a separate order, this time for two of these instead of one, for higher power handling, and quicker delivery (and the hope that at least one of them would be good enough to build with), which was in time for me to continue my antenna project before the weather changes on me again.
