Product Overview:
This product is a DIY balun (balanced-to-unbalanced converter) kit. It uses high-quality components, features pre-drilled holes in the casing, and comes equipped with waterproof gaskets, O-rings, terminals, and M4 mounting rings, ensuring 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.
Features and Functions:
- High-Quality Components: High-quality components 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 splash protection; the casing includes waterproof gaskets and O-rings. For rainy/humid environments, it is recommended to apply sealant for enhanced waterproofing.
- Easy DIY Assembly: Pre-drilled holes in the casing eliminate the need for additional drilling; all accessories are included, requiring only soldering tools for assembly.
- Customizable Impedance: Includes 1.2 meters x 1mm enameled wire, allowing for the winding of baluns with various impedance ratios to meet different needs. - Transparent casing: Allows easy observation of the internal structure and wiring, facilitating assembly and inspection.
- Long-lasting components: JS-910B type pure copper thickened terminals (excellent conductivity, robust structure); M4 size 304 stainless steel lifting rings, corrosion resistant, suitable for outdoor installation.
- Spare capacitor: Includes a 100pF high-voltage capacitor (spare part, not required for all baluns).
