  1. Site Survey

  2. Introduction This section instructs you on how to perform a thorough site survey.

  3. Objectives After completing this module, you should be able to: • List the steps to conduct a proper site survey • Explain the installation plan to the customer (mounting locations, cable routing, etc.) • Keep the customer informed of any revisions, if they occur

  4. Site Survey Work Sheet

  5. Site Survey Pre-Arrival Determine the ODU Pointing Coordinates • DIRECTV receiver • Azimuth – left and right • Elevation – up and down • Tilt – clockwise and counter-clockwise

  6. Site Survey ODU Pointing Coordinates

  7. Site Survey Arrival Observe the Site • Look for obstructions, trees, buildings, future construction, etc • Look for the type of construction of the home, roof pitch, etc. Observe • Look for power and phone entry points to the residence Do not walk around the home until you introduce yourself to the customer.

  8. Site Survey Arrival • State who you are and who you are with • Show your badge • Greet the customer by Mr. or Mrs. and their last name • Confirm that the customer is over the age of 18 • Ask about animals and children Meet & Greet

  9. Site Survey Customer Communication • Confirm with the customer the services and equipment ordered • Show the customer the protection plan paper work, customer satisfaction checklist and receiver manuals • Look for items that could be damaged by you or your tools • Explain that you will be performing an internal and external site survey

  10. Internal Site Survey

  11. Internal Site Survey • Receiver location • Current television picture quality (benchmark) • Customer equipment configuration • Telephone jacks • Ask the customer if the have DSL service • Operating electric outlet > (Is this a switched outlet?) • Internal cable routing • Potential safety issues, pets, inaccessible parts of the property, etc.

  12. Internal Site Survey • Check the electrical outlets • It is advised to not install the IRD under the following conditions: • Open ground • Open hot • Open neutral • Hot ground reversed • Hot neutral reversed • Advise the customer of any problems

  13. Site Survey Work Sheet

  14. External Site Survey

  15. External Site Survey • Locate house utility ground • Locate power entry • Locate phone entry (NID – Network Interface Device) • Line of sight • Obstructions • Future obstructions • ODU mounting • Type of home construction • Cable routing • Determine installation requirements

  16. Site Survey Work Sheet

  17. External Site Survey Locating the Satellites Inclinometer Elevation – 0° to 90° • Compass • Azimuth - • 0° to 360°

  18. External Site Survey Practice Exercise • Locate the azimuth coordinates using the compass

  19. External Site Survey Practice Exercise • Locate the elevation coordinates using the inclinometer

  20. External Site Survey • Dial 360 degrees • 0 degrees is magnetic North • Needle points North • Align needle on 0 degrees, or North • Locate the azimuth degrees on the dial Using Another Type of Compass

  21. External Site Survey Clear Line of Sight • Obstructions • Tree growth • Foliage in the spring • Buildings • New construction

  22. External Site Survey Clear Line of Sight?

  23. The DIRECTV Fleet

  24. External Site Survey Clear Line of Sight • Programming required • Satellite locations • Determine satellites used based on ODU types from the work order, (99°, 101°, 103°, 110°, and119°), as well as second ODUs for satellites at 95° and 72.5° • 10° on each side • Future upgrades

  25. External Site Survey Clear Line of Sight

  26. External Site Survey Clear Line of Sight

  27. External Site Survey Clear Line of Sight

  28. External Site Survey Bore Sight • What is bore sight?

  29. External Site Survey The LNB Arm The Satellite

  30. External Site Survey Bore Sight

  31. 110° 103° 99° 101° 119° Site Survey – Line of SightAzimuth Denver, Colorado Azimuth required to see the 101° satellite “bore sight” = 166° Los Angles, CA Azimuth required to see the 101° satellite “bore sight” = 137° Orange, NJ Azimuth required to see the 101° satellite “bore sight” = 231°

  32. External Site Survey Line of Sight - Elevation • The satellites orbit 22,300 miles from Earth near to the equator line • North America is between 26° N and 71° N above the equator

  33. Site Survey:Review the Plan Customer Communication • ODU location • Cable route • Receiver locations • Additional charges • Get approval

  34. Summary Now that you have completed this section you should be able to: • List the steps to conduct a proper site survey • Explain the installation plan to the customer (mounting locations, cable routing, etc.) • Keep the customer informed of any revisions, if they occur

  35. Exercise • Written Exam • Place site survey steps in the correct order • Hands-on • Use a DIRECTV receiver to locate the azimuth, elevation and tilt of the ZIP codes provided • Locate utility ground • Use the compass and inclinometer • Role Play: Customer Communication

  36. Thank you!
