A Closer Look at the Rocketfish 4K HDMI Premium Cable (12 ft) Supporting 4K, HDR, 18 Gb/s

The Rocketfish 4K HDMI Premium Cable (12 ft) is one of the many cable products sold at Best Buy that promotes 4K Ultra HD, HDR and 3D HDMI outputs with Ethernet and ARC support on its packaging. This 12 ft / 3.7 m cable is HDMI Premium Cable Certified which according to the Premium HDMI Cable Certification Program helps to ensure 18 Gb/s (4K@60Hz) video streaming and EMI testing. 

The Rocketfish 4K HDMI Premium Cable (12 ft) is UL Listed as a computer-interconnection cable assembly and also comes certified for in-wall installation with 24K gold plated connectors to link up your HDMI enabled 4K or HD TV's or displays, and computers or other devices.

Using the GRL DI20 cable tester to test the insertion loss through the Rocketfish 4K HDMI Premium Cable (12 ft), we can see the cable has about the same overall signal integrity performance when compared to the AudioQuest Sky 4K Ultra HD HDMI Cable (12 ft) even though they are the same length. The Rocketfish 4K HDMI Premium Cable (12 ft) also has slightly lower loss under 10 GHz despite being a lot more cheaper than the premium-priced AudioQuest Sky 4K Ultra HD HDMI Cable (12 ft) (see review here).

Here's how the Rocketfish 4K HDMI Premium Cable (12 ft) looks like after unboxing.
