Digital Installation - 1 Modern Communication & Broadcast System (MCBS) - 60cms

 By the End of this session you will be able to:  Identify the components of dish Antenna.  Explain functions of each components.  Assemble the components of dish Antenna.  Install the complete dish antenna. Objective

Component Identification

Components  Reflector  Antenna Bracket  Elevation Bracket  LNBF arm with cap  LNBF Clamp  Mast  Struts-2  Foot mount  Nuts, Bolts & Screws

 Reflector intercepts the incoming signal from the satellite and reflects to a common point called focal point. Reflector Reflector’s Rear view Rim Reflector’s Front view

Function of Reflector LNBF Reflector

 It helps in fixing Reflector to LNBF Arm and Elevation Bracket. It is fixed on the rear side of Reflector. Antenna Bracket Direction to hold the Bracket Up ward Direction

 Side view of the Antenna Bracket Antenna Bracket

 Elevation bracket is for elevation & azimuth angle setting and to fix Antenna bracket & Mast. Elevation Bracket Bolt fixed here acts as Stopper Side View
