Hi
I came across a question in the Comptia Network + Mock questions about the type of cable used for 10base2. Looking throught the exam outline it only indicates knowing about two coax types RG-59 and RG-6 However i thought that 10base2 runs on RG-58 does anybody know what the right cable is? Thankyou Stuart |

RG6 = satillite Higher throughput / at higher signal freq. / more expensive
RG59 = everything else http://www.abccables.com/info-rg59-vs-rg6.html Quote: RG59 has a little less signal reduction, or attenuation, over 100 feet. The shielding on RG59 does not work quite as well to maintain Gigahertz level signals inside of the center conductor. RG6 has a better design for maintaining the signal levels inside the center conductor. This is the reason RG6 has become the standard for broadband CATV and satellite systems. A basic rule of thumb is to use RG6 for any Rapid Frequencies, and use RG59 for video frequencies. RG6 has an aluminum braid and an aluminum shield. RG59 comes with a copper braid, and in some instances, an aluminum braid and shield, although this is quite rare. For any broadband CATV or satellite system, RG6 is recommended by all the experts. For any signals that are video frequencies RG 59 will be adequate but RG6 could be used as well. |

Thankyou, so forget any reference to RG-58?

The main difference between 58 (std, A, B, C) series and 59 (A, B) series is in impedence / ohm rating.
RG58 has a distinct impedance of either 50 or 52 ohm RG59 has a distinct impedance of either 70 or 73 - 75 ohm |

Cable television uses RG-59 (75 ohm). |
