Designed for both transmitting and receiving applications, it delivers a focused 100° radiation pattern with 4 dBi gain to significantly increase RF reliability while rejecting rear off-axis interference. Ideal for broadcast studios, FOH mixing stations, live venues, and multi-channel rack distribution. Available now at WG Electronic with fast UAE delivery.
Targeted Wireless Coverage with the Sennheiser AD 1800 Antenna
The Sennheiser AD 1800 is a high-performance passive directional paddle antenna designed to optimize RF signal transmission and reception in high-density 1.8 GHz wireless environments. By narrowing the coverage angle, it concentrates signal strength toward performers while suppressing ambient RF noise from the rear and sides.
As an essential component in our Sennheiser RF systems catalog, the AD 1800 enhances link reliability for both stationary wireless receivers and in-ear monitoring (IEM) transmitters operating across the 1400–2400 MHz frequency band.
