Electro-Voice Active Log Periodic Antenna, 470-960MHz

The Electro-Voice Active Log Periodic Antenna (ALPA) is a high-performance RF accessory engineered to extend system range and improve reception for professional wireless setups. Covering the essential 470–960 MHz band, this active directional antenna helps you pull in the desired RF signal while effectively rejecting unwanted interference. Its switchable 3 dB and 10 dB amplified gain gives you the flexibility to adapt to different environments, from tightly packed venues to open-stage environments. Designed to mount on a standard threaded microphone stand, the ALPA delivers fast, secure deployment without sacrificing performance. If you’re expanding an existing wireless system or planning a new installation for events, broadcasting, or studio work, the ALPA provides reliable, front-end signal enhancement and directional focus that can make the difference between a marginal link and a rock-solid connection.

• Broadband coverage: 470–960 MHz to match the most common wireless microphone and in-ear monitor bands, maximizing compatibility and reducing the need for multiple antennas.
• Switchable gain: Easily select +3 dB or +10 dB of amplified gain to tailor sensitivity to your venue size, RF environment, and system requirements.
• Active design: Integrated preamplifier boosts weak RF signals, extending range and reinforcing link budgets for reliable performance in challenging RF spaces.
• Directional performance: Log-periodic configuration concentrates reception toward the desired transmitter while suppressing stray RF, improving signal-to-noise ratio and overall clarity.
• Mounting flexibility: Mounts quickly and securely on standard threaded microphone stands, enabling on-the-fly repositioning and versatile placement on stage, in studio, or at venues.

how to install Electro-Voice Active Log Periodic Antenna

• Attach the ALPA to a standard threaded microphone stand using the built-in mounting thread and secure it firmly to prevent movement during use.
• Connect the RF coax from your wireless transmitter/receiver to the antenna input with a low-loss feed line to preserve signal integrity.
• Select the appropriate gain setting on the antenna: +3 dB for typical environments, or +10 dB when operating in higher-RF-noise venues or longer cable runs.
• Orient the antenna toward the anticipated RF source, then adjust azimuth and elevation to maximize received signal while suppressing interference from off-axis directions.
• Route and secure cables to minimize movement, protect connections from accidental disconnection, and verify a clean RF link before going live.
