AKG SRA2EW - SRA2 EW Passive Omnidirectional Broadband Antenna

AKG SRA2 EW - Passive UHF Broadband Directional Antenna (470–952 MHz, 6 dB, 70°)

The AKG SRA2 EW is a wideband, directivity UHF antenna designed to improve reception or transmission in wireless microphone and in-ear systems . Its passive construction requires no power and offers 6 dB gain and a 70° coverage angle , helping to compensate for cable losses and reject unwanted signals outside the main lobe. It operates over an extremely wide range of 470–952 MHz , incorporates a 50 Ω female BNC connector and is waterproof for indoor or outdoor use. Includes 3/8” and 5/8” thread adapters for mounting on a microphone stand or bracket.

Main features

• Ultra-wide band 470–952 MHz compatible with most professional UHF systems.
• Directional (70°) : higher signal-to-noise ratio and control against lateral interference.
• 6 dB antenna gain to compensate for losses in short coaxial cable runs.
• Passive : no power supply required; recommended for cable lengths ≤ 10 m .
• Professional connectivity : 50 Ω female BNC output.
• Water-resistant construction and black finish, suitable for indoor/outdoor mounting.
• Includes 3/8” and 5/8” thread adapter for mounting on standard supports.
• Lightweight and compact size : approx. 240 × 230 × 26 mm , 250 g .

Product benefits

• More useful signal, less noise : Directivity reduces multipath and unwanted off-axis RF.
• Easy installation : 50 Ω BNC connector and thread adapter included for feet or tripods.
• Total versatility : valid as a receiving or transmitting antenna in wireless microphones and IEM.
• Reliability on tours and events : waterproof design for variable weather conditions.

Use cases

• Signal reinforcement in UHF microphone receivers located on the side/FOH.
• Links for in-ear monitoring (IEM) systems in medium-sized venues.
• Fixed installations (theaters, auditoriums, temples) where directed coverage is required.

Frequently Asked Questions

• Is it omnidirectional? No. The SRA2 EW is directional . If you need omni coverage, the AKG alternative is the RA4000 EW (passive and omnidirectional).
• Does it need power? No. It's a passive antenna; we recommend using it with cables ≤ 10 m to minimize loss.
• Can it be used for transmitting and receiving? Yes. It can be used as a receiving or transmitting antenna, depending on the application.
