| Coaxial Cables |
Coaxial cable is a power cable with an inner conductor surrounded by a flexible, tubular insulating layer, which is enfolded by a tubular conducting shield; the inner conductor and the outer shield share the same geometric axis.
|
Coaxial cable is used in applications such as connecting radio transmitters and receivers with their antennas, Internet connections, and distributing cable television signals. Coaxial cable can be installed next to metal objects such as gutters, without the power losses that occur in other types of transmission lines, as it provides protection of the signal from external electromagnetic interference.

RG (Radio Guide) designations are mostly given to identify compatible connectors that fit the inner conductor, dielectric, and jacket dimensions of the old RG-series cables. Owed to television, RG-6 is the most commonly-used coaxial cable for home use, routing cable television signals to and within homes. RG-6 cables have become the standard for cable television (CATV), mostly replacing the smaller RG-59 in recent years.

CATV distribution coax typically has a copper-coated steel center conductor and a combination aluminum foil/aluminum outer shield, typically with low coverage (about 60%). RG-6 type cables are also used in professional video applications, carrying either baseband analog video signals or serial digital interface (SDI) signals; in these applications, the center conductor is ordinarily solid copper, the shielding is much heavier (typically aluminum foil / 95% copper braid), and tolerances are more tightly controlled, to improve impedance stability. |
| HitekNOFAL RG/6U - 18 AWG BC 74 & HitekNOFAL RG/6 - 18 AWG CCS 75 |
| The two types of coaxial cable ensure low loss at high frequency for cable television, satellite television, and cable modems. U stands for ‘Universal'; AWG denotes ‘American wire gauge'. RG-6 cables are typically fitted with diverse types of connector at each end. In CATV distribution applications, these are mainly F connector style; in professional baseband video, BNC connectors are used; and in consumer audio/video applications other than RF and CATV, RCA plugs are needed. Our cables come with a special PVC (Polyvinyl chloride) outer jacket designed for use in ventilation ducts to meet fire codes. |
| HitekNOFAL RG11- 14 AWG CCS 73 |
| This type of coaxial cable is best suited for long drops and underground conduits. |
| HitekNOFAL RG-59/U - 22 AWG BC |
| Used to carry baseband video in closed-circuit television, this type of coaxial cable has poor shielding but carries an HQ HD signal or video over short distances. |
