The CI 118-1 antenna is a four-through-hole-mount, low-drag, low-profile, boat-style marker beacon antenna with a BNC port. It features a 75 MHz frequency that supports high-sensitivity marker beacon receivers and is suitable for bottom mounting with both light and heavy fixed-wing single-engine and multi-engine aircraft. It is DC grounded to minimize accumulation of precipitation static and is Skydrol and rain erosion resistant.
