The DB-218SAT is a complete 2 Meter/440 MHz OSCAR antenna system. It contains the crossboom assembly with necessary phasing lines, relays, and hardware. It includes left and right circuitry switching to reduce fading. True RF switching elements are rated at 200 Watts and improved VSWR for higher efficiency. Feed points are encapsulated and weather protected for longer life. Made of fiberglass, the crossboom maintains the integrity of the circularity pattern.
