Sound Devices Astral VHF Whip Antenna (SMA)

Flexible VHF Antenna for Sound Devices Wireless Systems
The Sound Devices Astral VHF Whip Antenna (SMA) is a straight, flexible whip antenna designed for use with Sound Devices wireless systems that operate in the VHF frequency band. This antenna comes with an SMA connector and is tailored for reliable performance in the 169–236 MHz range. With a cut-to-length design, it allows users to fine-tune the antenna length for maximum RF efficiency based on the operating frequency.

Optimized for 169 to 236 MHz VHF Spectrum
Built to support VHF transmission, this antenna is optimized for use across the 169–236 MHz frequency range—ideal for Sound Devices transmitters and receivers like the A20-TX and A20-RX equipped with SpectraBand technology. It delivers consistent RF performance in environments where UHF congestion is a concern or where VHF is preferred for its extended propagation characteristics.

Customizable Length for Precise Tuning
The whip-style design of this antenna allows users to cut it to the desired length based on their tuned frequency, improving overall transmission and reception efficiency. This is especially useful for audio professionals who need to fine-tune their wireless systems to match exact channel frequencies for minimal signal loss and maximum range.

Flexible and Durable Design for Field Use
The antenna's flexible construction helps prevent damage during demanding productions, while its low-profile design reduces the chance of snagging on clothing or gear. It’s well-suited for use in mobile audio rigs, bag-based setups, and even mounted on performers or talent in live or broadcast environments.

Compatible with SMA Connector Wireless Gear
Outfitted with an SMA connector, this whip antenna integrates seamlessly with Sound Devices transmitters and receivers that accept SMA antenna connections. It’s a direct fit for modern systems without requiring adapters or modifications, ensuring fast and secure connection in any setup.
