Radar reflector

A passive reflector of radar emissions, usually made of

three plane surfaces meeting at right angles to each other. The result forms

eight three­-sided funnels. Such reflectors are mounted on buoys and beacons so

that ships equipped with radar can locate them. Any private craft, of whatever

material of construction, should carry a radar reflector if she moves in waters

where she may encounter ships. The reflector should be as large as feasible,

and certainly not less than 15 inches, and preferably at least 18 inches,

across the diagonal. The reflec­tor should be hung from three of its corners,

so that one ‘funnel’ faces up to the sky as if to collect rain. That will leave

six funnels to face outward around the horizon.
