Mark, W8BBQ shows how easy it is to use the DX Engineering Custom Cable Builder. Just four easy steps! The builder lets you select the precise cable type, length and connectors you want on each end. Mix-and-matching connectors is OK too! Also use the tool to create copper braid assemblies for your specialized grounding applications. RG400 Custom Cable assemblies are being added soon! Each custom Qcoax cable is hi-pot tested by our technical staff before it leaves our facility. Find the Custom Cable Builder on the DXEngineering.com home page or click here!
