The lesson
Make a spec sheet from line drawings and spare lists, and let the restraint signal that the engineering is solid.
The cover is a white page with a letterspaced "STARLINK | STANDARD 4 X SPECIFICATIONS" header and a single outline drawing of the dish on its stand, with no photo or copy. Later pages pair dimensioned line drawings of each component with a short hairline spec list.
Don't strip the content if your buyer needs persuasion; this format assumes a reader who already wants the product. Keep the drawing-plus-list pairing and exact dimensions.
