Reflector, feed and installation
Reflector and assembly
Stretch-formed, doubly contoured panels, matched radials and hub; self-aligning main reflector and factory-assembled hub and mount.
Structure
The webpage lists a galvanized pedestal, aluminum back structure and stainless-steel hardware. The PDF instead lists galvanized steel reflector backup structure; confirm the supplied structure.
Feed options
Webpage: field-changeable C/Ku/Ka feeds, circular/linear polarization and CP/LP switching. PDF: X-band capability and LP adjustable feed. RF values below apply to the listed Ku-band feed.
Optics and approvals
Webpage: Cassegrain. PDF: Ring-focus design. Confirm the project drawing. The PDF approval and radiation-pattern references apply only where supported by documents for the selected configuration.
