UNUN Balun 9:1  Type 61 core material giving extremely flat bandwidth.
Note these cores are expensive and beware cheap 9:1's will not perform as you expect.

Stainless steel hardware. 
Wire is Class H 212 Deg Celsius double coat enamel and covered in taflon sleeve.

High Quality means paying for what you get  Cheap = very inefficient = very hot.
