QR500 Coaxial Cable

QR500 cable aluminum tube cable refers to the physically foamed coaxial argon arc welding aluminum tube cable produced in the standard GY/T135-1998, which is widely used in satellite and television cables, including cable television, digital television, closed-circuit television, video transmission, security system and satellite television. Trunk cable, branch distribution cable.

 

QR500 Coaxial Cable - Product Description

The QR500 Coaxial Cable is a high-performance RF cable designed for a wide range of applications. This cable offers low loss, high power handling, and excellent shielding to ensure optimal signal integrity.

Construction

The QR500 features a solid conductor core made of 2.75mm copper. This is surrounded by a precision air dielectric, which provides excellent insulation and signal stability. The cable is then wrapped with a double helix copper braid shield, which offers superior electromagnetic interference (EMI) protection. The outer jacket is made of a weather-resistant polyethylene (PE), which further enhances the cable's durability and longevity.

Frequency Range

The QR500 offers a wide frequency range of up to 6 GHz. This makes it suitable for a range of applications, including telecommunications, wireless networking, and broadcasting.

Low Loss and High Power Handling

Thanks to its solid copper conductor and air dielectric, the QR500 offers extremely low attenuation, or signal loss. This means that signals can travel long distances without experiencing degradation or interference. The cable also has a high power handling capacity, allowing it to carry high-frequency signals with ease.

Shielding

The double helix copper braid shield on the QR500 provides excellent EMI protection, ensuring that signals are not affected by external interference. The braided shield also helps to reduce noise and crosstalk, ensuring that signals remain clear and consistent.

Weather Resistance

The QR500's outer jacket is made of a weather-resistant PE material, which makes it suitable for use in outdoor applications. The cable is also resistant to moisture, UV radiation, and other environmental factors, ensuring reliable performance even in harsh conditions.

Applications

The QR500 is ideal for a range of applications that require high-quality RF signal transmission. It can be used in telecommunications applications, including cellular networks and satellite communication systems. It is also suitable for wireless networking, microwave communication, and broadcasting applications.
