Kabel CCTV RG59-S adalah koaksial single kabel RG6 dengan panjang hingga 500 m per rol. RG6-S cable is heavier gauge and has thicker insulation and better shielding. It is best for high bandwidth or high frequency applications such as Internet, Cable TV, and Satellite TV signals. RG 6 is generally a much better choice for your CATV, satellite, TV antenna, or broadband internet.
|Conductor||Cooper clad steel|

|Dielectric Insulation||Foam PE|
|Inner Braid||34AWG aluminium 0.16X34|
Coaxial cables use RG ratings to distinguish between the different kinds of cables. RG is an old military term that stands for “radio guide.” The number distinguishes the different cable specifications that randomly assigned, so don’t look for some type of order in the numbers. Literally dozens of coaxial cables have been made over the years, but the only ones that most people need to know are RG 6 cable and RG 59 cable.
Kabel RG6-S Coaxial Cable
RG6-S cable is heavier gauge and has thicker insulation and better shielding. It is best for high bandwidth or high frequency applications such as Internet, Cable TV, and Satellite TV signals. RG 6 is generally a much better choice for your CATV, satellite, TV antenna, or broadband internet. RG 59 is generally better for most CCTV systems. What you really need to consider are the frequency ratings your equipment uses. If your equipment uses higher frequencies (above 50 MHz), then you’ll want to go with RG 6. If your frequencies are lower than that, then you’ll want to use RG 59.
All of the new demands required by, satellite signals and broadband internet made it necessary to find a more effective coaxial cable. RG6 cable was designed to fulfill these requirements. It has a larger conductor, which gives you much better signal quality. The dielectric insulation was made thicker as well, which means it is much less likely to carry an electric current that could damage your sensitive electronics. RG 6 is also made with a different kind of shielding, which allows it to more effectively handle Ghz level signals.
Shielding prevents signal loss, and therefore preserves your signal quality. Coaxial cables usually come with two types of shielding: dual and quad. The more shielding you have, the better your cable will perform, especially in longer runs. The difference is in the amount of shielding provided. Dual shielding involves a bonded foil shield underneath a metal braid (RG 59 cable uses a copper braid and RG 6 uses an aluminum braid). Quad shielding has more layers of shielding and is usually more protected. However, newer coaxial cables are made with a 95% braid (most braids are only 60%), which allows them to perform better than quad shielded cables.
While newer shielding techniques have allowed us to cut signal loss to a minimum, there is always some signal loss. Here’s the breakdown of signal loss (attenuation) in decibels for 100 ft. of cable. Just remember, the longer your cable runs are, the more signal loss you will experience. That’s why it’s best to keep your installation lengths as short as possible.
RG 6 Signal Loss (in dB) per 100 ft:
- Loss at 50 MHz: 1.5 dB
- Loss at 100 MHz: 2.0 dB
- Loss at 400 MHz: 4.3 dB
- Loss at 900 MHz: 6.8 dB
- Loss at 1000 MHz: 7.0 dB
