RG-8 N-Type — QMA Tactical Cable Kit (2 × 20 m)
The RG-8 N-Type — QMA tactical cable kit includes two 20-meter cables designed to connect radio communication equipment and other devices with compatible interfaces. The cables feature N-Type — QMA connectors, a copper-clad aluminum center conductor, a physically foamed polyethylene dielectric, double shielding, and a PVC outer jacket. The cables are available in black or olive (RAL 6003).
Key Advantages of the RG-8 Cable Kit
- Double shielding: 100% aluminum foil and a braided shield made of 90% tinned copper wire help reduce external electromagnetic interference.
- Low signal attenuation: The cable is designed for RF signal transmission with specified attenuation values across the listed frequency range.
- Durable outer jacket: The PVC jacket protects the cable during everyday use.
- Convenient kit: Two 20-meter cables provide a total length of 40 meters.
- Compatible connectors: N-Type and QMA connectors allow connection to equipment with matching interfaces.
Applications
The RG-8 N-Type — QMA cable kit can be used to connect radio communication equipment, antennas, and other RF devices equipped with compatible connectors. Before use, ensure that the connectors, impedance, and operating frequency range are suitable for the equipment.
