The yagis are constructed from extruded Series 6000 silver anodised aluminium with the clamps being cast aluminium and fitted with stainless steel hardware.
Nominal feed impedance is 50 ohms with the matching circuit within the sealed driven element. The feed line is typically RG213 coaxial cable and fitted with an N plug connector. Some models are however fitted with a 75 ohm coaxial cable which acts as an impedance transformer. Please note: Do not alter the cable length. All elements are DC grounded.
