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

Discover the Electro-Voice PLPA Passive Log Periodic Antenna, a purpose-built solution designed to extend your system’s range and boost RF performance across the 470–960 MHz band. This compact, high-efficiency passive antenna focuses energy toward the desired signal while naturally suppressing interference from unwanted directions, delivering cleaner reception for wireless microphone links, in-ear monitoring, and RF distribution in live environments. The PLPA is engineered for fast, on-site setup, attaching effortlessly to a standard threaded microphone stand for flexible placement on stages, studios, or field shoots. Its directional design helps you maximize signal quality in busy venues where RF traffic is dense, providing a reliable path to better audio and video synchronization with fewer dropouts. Because it’s passive, the PLPA requires no power and adds no active circuitry to your rack, reducing maintenance while delivering tangible range gains. Whether you’re running a small corporate presentation or a full-scale live production, this antenna helps you reach farther with greater confidence.

• High-efficiency passive gain: The PLPA delivers approximately 10 dB of passive gain within its 470–960 MHz coverage, meaning you’ll experience a noticeable boost to the strength of your target signals. This gain translates into longer reach, more stable connections, and improved resilience in environments with RF crowding. In practice, users often notice fewer dropouts and clearer audio when the receiver can “see” more of the intended signal in challenging venues.
• Broad 470–960 MHz frequency range: This wide span makes the PLPA suitable for a variety of wireless systems and applications, from modern multi-band wireless microphone setups to RF distribution networks used in broadcast and event productions. The broad band coverage allows you to accommodate different channel plans and future-proof your investment against evolving wireless standards, all without swapping antennas.
• Directional pattern for interference rejection: The log-periodic design is purpose-built to favor signals coming from the direction you point the antenna toward, while attenuating signals and noise from unwanted directions. This directional behavior is especially valuable in venues with multiple RF sources, tall stage rigs, or adjacent transmissions, helping your receiver maintain a cleaner signal with less competing RF energy.
• Easy, stand-mounted installation: The PLPA is designed to mount on standard threaded microphone stands, enabling rapid placement and flexible positioning. You can swivel and tilt the antenna to optimize line-of-sight to the transmitter, steering RF energy toward the area where your performers and presenters are most active. The stand-mount design keeps cables organized and reduces the footprint of your RF setup on crowded stages or control rooms.
• Passive, low-maintenance design: With no active electronics or power requirements, the PLPA minimizes maintenance concerns and device failure points. There’s no power injector to monitor, no cooling needs, and no extra cables to run. This simplicity translates to lower total cost of ownership and a dependable addition to both touring rigs and fixed installations, where reliability matters as much as performance.

How to Install Electro-Voice PLPA

Installing the PLPA is a straightforward process that takes moments, yet yields meaningful gains in RF performance. Follow these practical steps to maximize the antenna’s effectiveness and ensure durable operation throughout a production or rehearsal cycle:

• Attach the PLPA to a standard threaded microphone stand. Ensure the stand is stable and positioned where it won’t be bumped by performers or equipment during use.
• Orient the antenna toward the anticipated signal source. Because the PLPA is directional, aiming it toward the transmitter (or the area containing most active wireless devices) helps harness the peak of its gain and improves reception.
• Secure the connection to your RF system. Route the coaxial cable from the PLPA to your wireless receiver or RF distribution hub, using proper strain relief and cable management to prevent accidental disconnections or mechanical stress.
• Check for obstructions and interference. Make sure there are no large metal structures, reflectors, or bodies between the antenna and the transmitter that could degrade performance. Small adjustments in tilt or rotation can yield noticeable improvements in signal clarity.
• Test and tune. Power up the system and run a quick range check, scanning for any dropouts or noisy channels. If needed, slightly adjust the antenna’s angle or direction to find the most stable operating point.
