WINK-27 is a foldable oil-cooled base-loaded CB antenna designed for vehicle communication across 26–28 MHz. It uses a 50 Ω vertical omnidirectional configuration, provides an 800 kHz bandwidth at SWR 2:1, and supports up to 200 W power handling. The oil-cooled lower section is designed to help manage core heat, while the transparent lower housing allows visual checking of the oil level. Its foldable joint and steel lever support easier positioning for installation and storage.
