Power/Video Cable Quality Comparison
|
There are claims made for a "Pro Looking" cable as " True RG59 U with 18/2 power wire"
Lets take a closer look at the so-called "True RG59U with 18/2 power wire cable" First,
scratch the coax cable conductor with a utility knife, and you will see a
white steel alloy color shows up under the thin copper coating. Bare copper shields are also required for CCTV applications. Cheap aluminum polyester foil shields are only used for CATV applications. Foil shields do not meet the RG59U standard. 18/2 power wire means 2
of 18 gauge power wire. Look at the ""True RG59U with 18/2 power wire
cable"" There is actually only one power wire with hair thin
conductors. Recapping, due to the sky rocking copper price, some cable companies and sellers are using steel conductor coated with copper to substitute copper. They also use single, or double cheap aluminum polyester foil shields to substitute for bare copper shielding, thus making the pro looking fat cables. Unfortunately, those copper coated steel conductors are not suitable for good CCTV applications. All our cables use bare copper conductors. Using a multi-meter, we compare a 150 ft ""True RG59U with 18/2 power wire cable"" purchased from another eBay seller with our 150ft Video, Audio and Power extension cable.
The "power cord resistance" on the 150 ft ""True RG59U 18/2"" cable is 11.3 ohms. The "power cord resistance" on our 150 ft Video, Audio and Power extension cable is 6.5 ohms Cables with lower resistance are superior. There is less voltage drop.
The "Video cord resistance" on the 150 ft ""True RG59U 18/2"" cable is 18.1 ohms. The "Video cord resistance" on our 150 ft Video, Audio and Power extension cable is 7.2 ohms Cables with lower resistance are better, as they will have lower video signal loss.
