KX6 coaxial cable is used for 75-ohm radio frequency and video-signal transmission in wireless communication, broadcasting, CATV, shared-antenna systems, subscriber lines, CCTV and related electronic equipment. When selecting KX6, buyers should confirm the required operating frequency, cable length, allowable attenuation, connector compatibility and installation conditions.

KX6 and KX8 are both 75-ohm coaxial cables in Xingfa's current product range, but they differ in physical construction and published attenuation.
Xingfa's KX6 uses a 7 × 0.2 mm bare-copper center conductor and has an approximately 6.10 mm overall diameter. For projects requiring a larger coaxial construction, buyers can also review Xingfa's KX8 coaxial cable, which currently uses a 7 × 0.4 mm BC/CCS conductor and has an approximately 10.20 mm overall diameter.
Based on Xingfa's currently published data, cable KX8 also has lower maximum attenuation than KX6 at comparable frequencies. For example, at 1000 MHz, the published maximum attenuation is 41.50 dB/100m for KX6 and 27.50 dB/100m for KX8.
KX8 is not automatically the right replacement for every KX6 installation. Before changing cable models, compare the operating frequency, transmission distance, allowable signal loss, connector compatibility, routing space and the equipment specification.

For installations where the smaller KX6 construction already meets the system requirements, there is no need to move to a larger cable. Where transmission distance or attenuation requirements differ, compare the KX8 specification before final selection.
Both KX6 and KX8 are 75-ohm coaxial cables, but KX8 has a larger published conductor and overall cable diameter and lower published attenuation at comparable frequencies. KX6 may be more suitable where its smaller construction already meets the installation requirements, while KX8 can be evaluated for projects with different transmission-distance or attenuation requirements.
Xingfa has manufactured coaxial cable since 1996 and currently reports five coaxial cable production lines with annual output of approximately 200,000 km. For KX6 sourcing projects, customers can submit the required cable specification, quantity, packaging and target-market requirements for OEM review.
