CCTV Coaxial Siamese with 2 power cable

Cable RG59-2P adalah Kabel CCTV coaxial siamese dengan 2 power cable. RG59 is good for lower frequency signals (<50 MHz) that makes it a good choice for a CCTV video surveillance system. Siamese coaxial cable consists RG 59 cable merged together with a 2C power cable. By using this type of cable wecan run the power and video for security cameras simultaneously, effectively cutting install time in half.

Fitur CABLE RG59-2P:

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 RG 59 Siamese Coaxial Cable

RG59 cable has been around for a long time. This cable used to be what most people used for their cable TV connection. However, modern signal requirements have made this cable less popular in the last few years. RG 59 has a smaller conductor than RG 6, which means that it can’t achieve the same signal quality as RG 6. The way its shielding is designed also means that it doesn’t keep Gigahertz level signals inside the conductor very well. This is why RG 59 probably isn’t a good choice for your TV or internet connection.

RG 59 is good for lower frequency signals (anything under about 50 MHz). That makes it a good choice for a CCTV video surveillance system. You can even make your installation easier by getting what’s called “Siamese coaxial cable”. RG59-2P cable consists of a RG 59 cable merged together with a 2C power cable. By using this  CCTV cable type you can run the power and video for your security cameras simultaneously, effectively cutting your install time in half. Also some older HD TV’s still use lower frequencies (around 37 MHz), making RG 59 a better choice for them.


Shielding prevents signal loss, and therefore preserves your signal quality. Coaxial cables usually come with two types of shielding: dual and quad (although some RG 59 cables still use single shielding). 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.

RG59-2P Signal Loss

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 59 Signal Loss (in dB) per 100 ft:

  • Loss at 50 MHz: 2.4 dB
  • Loss at 100 MHz: 3.4 dB
  • Loss at 400 MHz: 7.0 dB
  • Loss at 900 MHz: 11.1 dB
  • Loss at 1000 MHz: 12.0 dB

If you are running cable outside, it has to have added protection from the weather and the elements. Outdoor cable has been specially designed to resist the elements. They come with a PE (polyethylene) jacket instead of the standard PVC jacket used in most coax cables. The PE jacket makes this cable extremely resistant to cold weather, moisture, chemicals, abrasion, cutting, and even lightning.

When we bury a coaxial cable, moisture becomes even more of an obstacle. Without added moisture protection, you risk moisture and contaminants entering into the cable and corroding your shielding and conductor. Direct burial cable has the special PE jacket that outdoor coax has, along with a special gel-like substance in the jacket that blocks water and moisture corroding your conductor and damaging your signal.
