Description
AKG RA4000B/EW Antenna
The AKG RA4000B/EW is a compact, actively amplified antenna designed for wireless microphone systems operating across a wide frequency spectrum. Its lightweight construction and universal mounting adapter integrate seamlessly into home and project studios, while the built-in amplifier compensates for signal loss over extended cable runs—critical when routing wireless receivers away from recording spaces or to distant monitoring positions.
Coverage & Signal Performance
This antenna delivers 360° omnidirectional coverage across the 470–952 MHz band, making it compatible with a broad range of wireless mic frequencies used in contemporary recording sessions. The 18 dB total gain and 17 dBi antenna gain ensure reliable signal pickup even when RF conditions degrade due to building materials or dense mic setups, and the remote-powered amplifier maintains signal integrity through cable runs up to 300 meters—enabling flexible receiver placement and cleaner studio floor configurations.
Studio Integration & Placement
The 220 mm length and 65 g weight keep the antenna discreet and easy to reposition as your session evolves. Its waterproof plastic construction works reliably in both controlled studio environments and location recording setups, while the included universal stand adapter accommodates standard 3/8" and 5/8" mounting screws, allowing quick installation on mic stands, boom arms, or overhead rigging to optimize reception and minimize floor clutter.

Frequently Asked Questions
What wireless microphone systems is this antenna compatible with?
The RA4000B/EW works with any wireless system operating in the 470–952 MHz band. It connects via a standard BNC female output connector and requires 8V remote power delivered through the antenna cable, making it compatible with AKG, Shure, Sennheiser, Audio-Technica, and most other professional wireless systems in that frequency range.
How far can I run a cable from this antenna?
The built-in remote-powered amplifier supports cable runs up to 300 meters while maintaining signal integrity. The 50 Ohm RF output impedance ensures proper matching and prevents signal loss over these extended distances.
Can I use this antenna outdoors?
Yes. The antenna features waterproof plastic construction designed for both indoor and outdoor use, making it suitable for touring, outdoor festivals, and permanent venue installations.
How do I mount this antenna?
The antenna includes a universal stand adapter that accommodates standard 3/8" and 5/8" mounting screws, allowing quick installation on microphone stands, ceiling poles, rigging hardware, or other standard mounting points. The compact 220 mm length and 65 g weight make positioning flexible.
What does B-Stock mean?
B-Stock means the antenna is fully functional with no defects in performance. It may have minor cosmetic imperfections from handling or display, but operates identically to new units and carries the same RF specifications and gain characteristics.
Do I pay sales tax on this order?
