There are a few reasons why you may find yourself installing your own Lag Screw system and if this is the case you will want to take some measures to insure that you do a professional quality job. All of the leading satellite TV service providers do free installation on up to three rooms in your home when you sign up but it is only three rooms and its only when you sign up. If you want more rooms done or you move to another residence its up to do it or pay for the service.
Step one, is to make sure that you have all of the right tools and hardware that you will need for the job and the only way to do this is to make a list of everything that you will need. You can rent tools that you need at a rental yard or at most of your local franchise hardware establishments such as Home Depot. Assuming that you have all of the tools that you are going to be using then its time to get started.
The most important part of your job is installing the satellite dish, because it has to be positioned for optimal reception and at the same time be firmly attached to a solid surface. It doesn't hurt to go out in your community and take a look at how other satellite dishes have been attached to homes and businesses for inspiration. Scout around your home for a place high on your roof or on an upper deck that has a clear shot of the southern sky.
Many times its an end barge rafter that people end up attaching their dish to but it can also be an outside wall on the home or a sturdy pipe extending out of the roof. Before you attach the dish scout out in the attic to make sure that you are going to be able to run the cable to the dish and if there is a problem you might want to find another place to mount it. Mount to dish using new hardware onto solid wood, meaning that you want to run your screws into the framing members inside of the wall if it is on an outside wall.
Pre-drill your holes and use nice big new lag bolts that are long enough to attach well. When you run your cable, you will want to attach it well to any walls and you don't want to tear up your home when you do it. If possible run it through the attic as much as you can and you can access interior wall cavities by drilling through the walls top plates in the attic. You may have trouble accessing your entire home through the attic, so you will most likely need a long "poke stick" to get the cable to where you need it to go.
It can be blazing hot in an attic during the day, so you may want to consider working at night when you do the job. If you need to run the cable out of the attic to the outside of your home, do it at a vent block and never go through the roof of the home or you will cause a leak. When you run the cable inside of your home do clean work and make sure that it is ran tight along the base of any walls or in the corners of Hex Lag Screw. You will need to use a compass to establish the final trajectory of your satellite dish.
