Fibreglass 1/4 wave tapered from 6.5mm to 4mm with 5/16" fitting coated with polyolefin black or white. The M6-1 works best when mounted onto a bracket that is as close to the surface of the ground plane as possible such as the BMS mount (Z brackets are not recommended with this antenna).

Recommended Accessories - UL12BNC or UL12C with BMB or Mag12C Note: You can use a spring SAL or SAO but the antenna will need to be re-tuned on the spring
