RG-8 coaxial cable for Alientech DUO II, DUO III QMA–QMA, 20 m, 2 cables is a heavy-duty professional RF cable that provides better signal quality and reduced signal loss when connecting Alientech DUO II and DUO III antennas. The set includes two coaxial cables of 20 meters each with QMA to QMA connectors. RG-8 features an aluminum inner conductor with copper cladding, a foamed polyethylene dielectric, an outer conductor made of self-adhesive aluminum foil and tinned copper braid, and a black polyethylene jacket. The cable has a characteristic impedance of 50 ohms, capacitance of 78 pF/m, velocity factor of 85%, and a maximum operating frequency of up to 21 GHz. It weighs 80 g per meter, has a bend radius of 51 mm, and operates reliably in temperatures from –40°C to +80°C.
🫡 We are a team of veterans
We treat this cable as a key component of the communication link between the active antenna and Alientech DUO II/III equipment. In real operations, the quality of the coaxial line often determines actual signal losses, which is why using RG-8 with stable 50-ohm impedance, high-quality shielding, and low attenuation directly affects range, stability, and reliability. This is especially important for military UAV operators.

Commentary / comments
RG-8 in the QMA–QMA configuration is well suited for Alientech DUO II and DUO III systems where stable signal transmission at medium distances is required. The aluminum inner conductor with copper cladding combined with a foamed dielectric reduces dielectric losses, while dual shielding improves resistance to external interference. The 20-meter length provides flexibility in antenna placement without excessive signal degradation.
🎯 Who it is suitable for
Primarily for military UAV operators, reconnaissance units, and special forces using Alientech DUO II or DUO III systems who require a reliable transmission line with minimal signal loss. It is also suitable for professional drone operators and technical specialists working with active Alientech antenna systems.
