A dish antenna is a kind of parabolic dish which receives and intercepts microwaves from the communication satellites. This satellite dish, in turn, transmits those data transmissions and relays them into pictures and sound on our TV screen (Gosh I cannot imagine if these were not there, how I could have watched Manchester Untied against Liverpool or Arsenal??). These are very common these days and are convenient as well. If you are thinking of installing it by yourself, it is a great idea, though it could get a bit tiresome. But it will save the money which you would have given to a professional. So are you ready? Here goes.
- Complete satellite system
- RG6 coax cable
- Satellite signal meter(optional)
- 6" magnetic level
- 7/16" wrench
- 1/2" nut driver drill bit
- Six 2" lag bolts
- Zip ties or black tape
- Staples or screw clips
- Decide upon the location of the TV antenna, in the direction corresponding to the specific area you are in. If you are confused, take a look at the direction of the nearby dish antennas. Now, bolt the mast down in solid, strong foundation. Do not forget to use a level and let the mast be able to move in all directions. This is a very important and necessary step for the setup.
- Now, tighten all the bolts on the mast. After that, set the antenna on the mast, but do not fix the screws just yet.
- Get your coax cable through the dish and then get it out at the end from the spot where there is low noise block down converter feedhorn (LNBF).
- Assemble the dish after connecting the cable to the LNBF, using the screws. For the correct skew and elevation settings for your area, check out your installation guide.
- The meter then has to be connected with the other end of the coax cable. Follow this up by turning your meter and sweeping your dish both left and right, approximately in the direction that your neighbor's antenna points to. Here, when it detects a satellite, your meter would indicate that.
- By now, you have got the idea that which position of the antenna catches the strongest signal, and you can adjust it and fix all the bolts on the dish.
- Check whether the vertical adjustment is proper as against the horizontal adjustment, which needs to be perfect. For adequately free up-down rotation of the antenna reflector, loosen the elevation screws a little.
- Again, keep moving the reflector gradually, till you come across the maximum signal reading on the meter. Follow this up with tightening of the bolts, while keeping the signal as strong as possible.
- Run the coax cable through, from the dish to the receiver. For better setup and design, it is good to use the zip ties and screw clips for attaching the cable to the mast.
- For getting the coax cable in the house, use a drill bit for drilling through the wall. After that connect the receiver with the cable. Typically the port would have an indication - 'in from satellite'.
- After connecting the receiver to the TV, plug it in. From here on, check out the installation manual where you would find further guidance. Finally, run the requisite tests, and you are done.
