Features: 

This product is a DIY balun (balanced-to-unbalanced converter) kit, using high-quality components. The housing has pre-drilled holes for positioning and comes equipped with waterproof gaskets, O-rings, terminals, and mounting rings, providing excellent waterproof performance.

The kit includes 1.2 meters (1mm diameter) of enameled wire, allowing users to wind baluns with various impedance ratios such as 1:1, 4:1, 9:1, 49:1, and 64:1.

- High-quality components: Excellent quality components for ensure stable performance and long lifespan, suitable for long-term outdoor use.

- Waterproof design: Each interface is equipped with waterproof gaskets, providing basic rain and for splash protection; the housing includes waterproof gaskets and O-rings. For rainy/humid environments, it is for recommended to apply sealant for enhanced waterproofing.

- Easy DIY assembly: Pre-drilled holes in the housing for eliminate the need for additional drilling; all accessories are included, requiring only soldering tools for assembly.

- Customizable impedance: The included 1.2 meters x 1mm enameled wire allows for the winding of baluns with various impedance ratios to meet different needs.

- Transparent housing: Allows easy observation of the internal structure and wiring, facilitating assembly and inspection.

-  components: JS-910B type pure copper thickened terminal blocks (excellent conductivity, robust structure); size 304 stainless steel lifting rings, resistant, suitable for outdoor installation.

- Spare capacitor: Includes a 100pF high-voltage capacitor (spare part, not required for all baluns).
