RG-8 Extension coaxial cables N-Type–QMA (2×20 m) are heavy-duty professional RF cables that provide better signal quality and reduced losses when connecting Avenger and Alientech DEIMOX antennas. The cable 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. This construction ensures stable electrical performance, low attenuation, and high mechanical durability. RG-8 operates reliably in temperatures from –40°C to +80°C, has a bend radius of 51 mm, and weighs approximately 80 g per meter, making it suitable for both field and fixed installations.
🫡 We are a team of veterans
We consider RG-8 a key component of the communication link between the controller and the active antenna. In real operations, cable losses are often the main source of signal degradation, which is why using RG-8 with stable 50-ohm impedance, high-quality shielding, and low attenuation directly affects range and reliability. This is critical for military UAV operators.

Commentary / comments
RG-8 offers clear advantages over thinner cables due to superior shielding and lower losses over long runs, which is especially important when used with high-power active directional antennas such as Avenger or Alientech DEIMOX. The aluminum inner conductor with copper cladding and foamed dielectric reduce dielectric losses, while dual shielding improves resistance to external interference.
🎯 Who it is suitable for
Primarily for military UAV operators, reconnaissance units, and special forces using active directional antennas like Avenger or Alientech DEIMOX who require minimal signal loss over long cable runs. It is also suitable for professional drone operators and engineering teams building reliable RF communication systems.
