How to Connect Satellite Coax Cable in a House

Install coaxial (coax) cable within your DirecTV (DTV) dish and receivers the way you need it to run. Join an old receiver to the system without incurring installation labor expenses by doing it yourself.

Choose a quality “RG6” coaxial cable for connection between the dish and each tuner.

Considering most Direct TV (DTV) DVRs and TiVOs hold dual tuners, consider operating two cables instead of one. In the state of the DTV High Definition DVR or DTV High Definition TiVO, assume three lines if you want to connect an “off-air” antenna to get local channels not available from DTV. If DVRs are not designed, placing one Cable will furnish a simple DTV receiver. 

Establish a ground block in a suitable location anywhere between the dish and before registering the home. It is permitted to locate the ground block inside the house, but it should be as adjacent to the point of entry as potential. If unable to buy a ground block to accept all inputs and outputs, it will be needed to add extra ground blocks to provide all the connections.

Connect a #10 copper wire between the house ground point and the grounding terminal screw of the new ground block. These two points must be connected. Use a clamp designed to connect the #10 wire to the house’s ground point.

Do not under any conditions disconnect or loosen existing ground links to install the new #10 wire. Leave sufficient ground wire to “thread” through every ground block(s) ground terminal. Route the cable and fasten it with staples to the mounting facade. Securely compress the ground terminal bolt to the ground wire.

Coax cables from every dish’s output end into one side of the ground section.

Roll a cable from any rooftop UHF/VHF/FM antenna to the same side of the ground slab as the dish coax.

Work the same number of cables driven into the ground block, between the ground block and a central location. A convenience closet, a point near the telephone distribution block, or an electrical board area is ideal—label the coax cables “dish” or another competent manner. Ensure to label the coax from a rooftop antenna if elongated from the ground block.

Drive cables from every tuner to the central area. Affix labels to every one of the cables – if two cables are attached to a single set-top box like the case for a TiVO or DVR in a living room, mark the cables “LR1” and the other “LR2” or some other significant term.

Select a multi-switch by deciding how many inputs and outputs are required. The number of inputs comprises the number of LNBs on the dish plus one. A dual LNB dish would need a three-input multi-switch. The additional information is to mix in an “off-air” antenna or CATV signal.

The number of outputs of the multi-switch equals the number of tuners (not the number of receivers or set-top boxes) in your system. For example, a method of three set-top boxes consisting of two DTV receivers and a DTV DVR or TiVO with two tuners would require a four output multi-switch. Of course, if you attach another receiver next, you’ll need a multi-switch with additional outputs.

Try to buy a multi-switch with enough different outcomes to allow your system to “grow.” Cascadable multi-switches can be installed “down-line” from other multi switches but must be recognized for that use.

Multiswitches become more valuable as the number of inputs and outputs gains. DTV will fix as many as needed free of charge when adding or changing equipment such as receivers or antennas. Of course, it’s best to allow DTV to do this, but there is no reason you can’t if the cost is not an issue.

Mount the multi-switch(es) and connect the dish coax cables to the dish input connector and the antenna or Cable TV coax to the antenna input connector. Next, attach the coax cables from the receivers to the multi-switch output connectors. Snug the connectors to “finger tight” for now.

At the receiver end, connect coax cables(s) to each tuner input(s). The satellite cables connect to the satellite inputs – it does not matter which one. If you run only one satellite cable, attach it to satellite input 1. If this is a position requiring an off-air antenna input, attach it to a “diplexer” input instead of attaching a cable directly into the tuner. The diplexer will have a diagram indicating satellite and UHF/VHF connections. The diplexer “satellite out” connects to the DTV receiver tuner, and the UHF/VHF can connect to the “antenna” or “CATV” input of the DTV set-top box OR even an FM Stereo receiver.

Check picture quality at each location. Change channels to test both tuners for TiVOs and DVRs. Alternatively, use the receiver’s set up pages to view signal strengths of each satellite and tuner. Check connections and hardware until satisfied.

Securely tighten the coax connectors along each Cable where ever they appear with a wrench, starting at the TV, receiver, multi-switch, and ending at the ground block or dish. Do not over-tighten.

Everything You Want To Understand About Coaxial Cable

Coax Cable

Coaxial Cable, sometimes known as a coax cable, is an electrical cable that transmits radio frequency (RF) signals from one point to another. Since the early 20th century, the technology has been around with these cables mainly being used to connect satellite antenna facilities to homes and businesses thanks to their durability and ease of installation.

RG cable: There are several types of coaxial Cable, which differ by gauge and impedance. The gauge indicates the Cable’s thickness and is marked by the radio guide measurement or RG number. The more powerful the RG number, the weaker the central conductor core is.

Coaxial Cable has a distinct thick, round shape because of its interior insulation layer. Therefore, its size makes it look very different from other types of Cable, like twisted pair or Ethernet cable. The most available sizes of coaxial Cable are RG-6, RG-11, and RG-59.

Coaxial cables are possible in a variety of colors, including black, brown, and white.

Coaxial cables are a favorite choice because their shielded configuration provides the center conductor to transmit data immediately while shielded from damage and interference.

Coaxial cables are primarily built up of these four various layers:

  • A center conductor, which is regularly a copper wire, which data and video travels through
  • Encompassing the copper wire is a dielectric plastic insulator
  • A braided mesh formed from copper then serves to shield the Cable from electromagnetic interference (EMI) 4. The outer layer is a plastic coating that shields the interior layers from damage
