SENNHEISER Antenna 578853 (718-790 MHZ)
✓ In Stock (24 available)
The Sennheiser 578853 is an official factory replacement flexible whip antenna engineered for Sennheiser professional wireless bodypacks and pocket receivers operating in the 718–790 MHz (C / Cw Band). Replacing older part numbers 531304 and SD91084, this antenna restores factory-standard RF performance when your unit suffers signal dropouts, interference, or physical antenna damage. Cut to an optimized 78mm length for efficient quarter-wave reception across the C-Band spectrum, it delivers reliable omnidirectional coverage for live stage, broadcast, and touring applications. A rubberized flexible sheath protects against sweat, bending, and everyday wear — while the simple threaded screw-on connection means tool-free installation in seconds. Compatible across Evolution Wireless G3 & G4, 2000 Series, and Tourguide EK 1039 hardware within the 718–790 MHz window.
