Coaxial Cable
PCT International’s MOCSY®7 75 Ohm coaxial cable is available in a number of different sizes and construction types which are used for different applications. All MOCSY7 coaxial cables are manufactured to very strict tolerances and are of the highest quality.  They meet all industry standards and specifications including those developed by the Society of Cable Telecommunications Engineers (SCTE), who creates international standards for many TV signal distribution products.
CABLE CONSTRUCTION
A) Center Conductor
The center conductor is a copper-clad steel wire which provides maximum signal transfer at RF frequencies and excellent strength during installation. The copper is metallurgically bonded to the steel per the requirements of ASTM B 566, Class 10 A.
Center Conductor Adhesive
A proprietary, specially designed adhesive is applied as a coating to the outer surface of the center conductor to keep moisture from the interior of the cable and to sustain overall cable mechanical integrity.
B) Foam Dielectric
Polyethylene (PE) is foamed to micro-cell structures to achieve the highest level of signal transfer through the cable, while maintaining structural and environmental integrity in the cable.
Center Conductor Adhesive - A proprietary, specially designed adhesive is applied to the outer surface of the center conductor which bonds it to the dielectric. This helps block moisture from the interior of the cable and also provides additional mechanical stability and integrity to the overall cable.
B) Foam Dielectric - Polyethylene (PE) is foamed to micro-cell structures to achieve the highest level of signal transfer through the cable, while maintaining structural and environmental integrity in the cable.
C) First Shield - The first shield is a laminated aluminum-poly-aluminum tape that is applied longitudinally to the foam dielectric core, and is also fully bonded to the dielectric, providing 100% coverage over the core. This is important as it minimizes signal leakage from the cable and ingress into the cable, and also provides superior shielding performance both before and after flexing.
D) Second Shield - The second layer of shielding is braided 34 AWG aluminum wire, which improves the shielding effectiveness of the cable, provides mechanical strength, and is available in a variety of coverage options.
E) Third Shield (when included) - The third layer is a tape which is similar to the first tape layer. It is also longitudinally applied, but is not bonded. The third shield provides improved shielding, which may be required in harsh environments. Cables that include the third shield are commonly called “tri shield” cable since there are three layers of shielding (first tape, braid, and second tape).
F) Fourth Shield (when included) - The fourth layer of shielding is braided 34 AWG aluminum wire. It provides the highest level of protection from signal egress and ingress. It is only required in areas with very high levels of RF signal interference. Cables with four layers of shielding are commonly called “quad shield” cable since there are four layers of shielding (first tape, first braid, second tape, and second braid).
G) Jacket - To protect the cable from the rigors of installation and the environment, high quality jacketing is used. There are two primary types of jacketing materials used, depending upon the application. For most indoor and outdoor installations, polyvinyl chloride (PVC) jacketing is used and is available in UV stabilized black, white, and neutral colors. For buried cable and conduit applications, a black or orange polyethylene (PE) jacket is used.
Flooding Compounds - For direct burial or conduit applications, in addition to the use of PE jacketing, flooding compounds are used between the outer shield and jacket. PCT uses Corrosion Guard™ flooding compound, which is a non-flowing amorphous polypropylene flooding gel, for Series 6 and 11 standard, tri shield, and quad shield constructions. Corrosion Guard protects shield components from corrosion. Corrosion Guard can also be used for aerial installations.
PCT manufactures the three standard sizes of coaxial cables in common use for in-home TV signal distribution networks. These are Series 59, Series 6, and Series 11 (commonly called RG59, RG6, and RG11). RG59 is the smallest, and RG11 is the largest. Due to high signal loss over distance, RG59 is not widely used any more. RG6 is the most commonly used size since it has an excellent trade off in price, size, handling and signal loss when compared to RG11. RG11 is the largest and has the lowest signal loss over length, but it is hard to install, bulky, and relatively expensive when compared to RG6 coaxial cables.
