Works well as 9:1 Unun core material
Solid ferrite core used in winding my 9:1 Unun. I have bought several of these in the past, and are very happy with them . Recommended.

Makes a great 49:1 Balun transformer
This torroid made a great 49: I Balun. With 63 ft of 14ga standed wire, I made a very nice antenna that is resonant on 40m, 20m, and well below 3:1 on the others which is within the range of my radio's internal antenna tuner to bring in. Made great DX contacts when camping!

Good deal on Toroid cores for Antenna and other RF applications
Got these to make baluns for end fed antennas. They have a good rating for inductance and low loss at HF frequencies.
