    For what signal run?

    If you mean from the LNB to the receiver, you need the bandwidth of RG6, %9 will drop off at the high end of the spectrum and you will have signal issues.

    Now if you mean the video out to a TV (AV OR s-video is way better BTW) RG59 has the full capability to work just fine, unless you need a performance cable for unique EMI/RFI issues.

    As LONG as your cable is ALL RG-6 cable you won't have an IMPEDANCE MISMATCH..... That can create ghosting in the RG-59 line.....and anything connected PAST the RG-59. But the splitters really aren't any different....

    RG6! (I haven't used RG59 since the late 90's!) It is better constructed and made with better quality than an RG59. Also, I hope you are not planing to hook your box to your TV with this stuff! You need a component or HDMI cable for that!

    Personally I use this one http://www.monstercable.com/productdisplay.asp?pin...

    You have to use RG6 for satellite.

    RG6 is designed to handle the Gigahz frequencies while RG59 was designed for the Kilohz and Megahz frequencies used by cable TV systems.

    RG6 is "not" better than RG59 or better constructed. It's just built for different uses.

    RG6 is a requirement for satellite receiver installation. RG6 has less loss and is more durable. However, all RG6 is not the same. If you have a long run (more than 20ft) then get the best quality you can. I recommend Belden.

    59 will work if its a short run ...but rg6 is whats recommended, if your going to run new rg6 cable, run two while your at it, in case you ever upgrade to dvr

    RG-59/U is a specific type of coaxial cable, often used for low-power video and RF signal connections. The cable has a characteristic impedance of 75 ohms. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System.

    It is often used at baseband video frequencies, such as composite video. It may also be used for broadcast frequencies, but its high-frequency losses are too great to allow its use over long distances; in these applications, RG-6 or RG-11 is used instead. In cases where the transmission distance is too great for these media, such options as UTP (unshielded twisted pair) or fiber optic can be used.


    RG-59 coaxial cable is commonly packed-in with consumer equipment, such as VCRs or digital cable/satellite receivers. Manufacturers tend to include only RG-59 cables because of its low cost (when compared to RG-6). However, given the short lengths provided (usually 4-6 feet / 1.2-1.8 m), this is generally sufficient for its typical use.

    RG-59 is frequently used to synchronize two digital audio devices, such as ADAT optical devices. This is called word clock.


    RG-58/U is a specific type of coaxial cable often used low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System.

    Most two-way radio communication systems, such as marine SSB, marine VHF, amateur, police, fire, WLAN Antennas etc., are designed to work with 50 Ω cable.

    RG-58 cable is often used as a generic carrier of signals in laboratories, combined with BNC connectors that are common on test and measurement equipment such as oscilloscopes. However, interconnecting equipment with multiple coax cables can lead to ground loops, which may pick-up 50-60 Hz fields from the AC mains.

    RG-58 was once widely used in "Thin" Ethernet (10BASE2), where it provides a maximum segment length of 185 meters. However, it has been almost completely replaced by Category 5 cable (unshielded twisted pair) and Wi-Fi in networking applications.

    RG-58 cable can be used for moderately high frequencies. Its signal attenuation depends on the frequency, e.g. from 0.11 dB/m at 50 MHz to 1.4 dB/m at 2 GHz.


    RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. The term "RG-6" itself is quite generic and refers to a wide variety of cable designs, which differ from one another in shielding characteristics, center conductor composition, and dielectric type. RG-6 was originally a military spec where RG means Radio Guide, but is now obsolete; in practice, the term "RG-6" is generally used to refer to coaxial cables with an 18 AWG center conductor and 75 ohm characteristic impedance.

    The most commonly-recognized variety of RG-6 is Cable television (CATV) distribution coax, used to route cable television signals to and within homes, and RG-6 type cables have become the standard for 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 braid 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.

    RG-6 cables typically are fitted with various types of connector at each end; in CATV distribution applications, these are typically F connector style; in professional baseband video, BNC connectors; and in consumer a/v applications other than RF and CATV, RCA plugs.

    Hope it helps.
