Sennheiser ADP UHF

The Sennheiser ADP UHF is a passive, directional paddle antenna that improves the range and reliability of wireless microphone and in-ear systems. Covering 470 to 1075 MHz, it focuses reception toward the stage and away from interference, making it a smart upgrade for Sennheiser EW-D systems and other UHF wireless gear.

Highlights

• Passive directional antenna for UHF wireless systems
• Wide 470 to 1075 MHz frequency range
• Typical gain of 5 dBi
• Approximately 100-degree apex angle at -3 dB
• Front-to-back ratio greater than 14 dB
• 50-ohm impedance with BNC female connector

Sennheiser ADP UHF: Better Wireless Reception

The small whip antennas that come with most wireless receivers pick up signal in all directions, including interference from behind and beside the receiver. A directional paddle antenna like the ADP UHF focuses on the area in front of it, typically the stage, while rejecting signals from the rear. That improves the signal-to-noise ratio of your wireless system, reducing dropouts and extending usable range.

The ADP UHF is passive, so it requires no power and has no DC path, making it simple to add to an existing setup.

Where to Use the ADP UHF

Directional antennas are especially helpful in large rooms, outdoor events, and installations where the receiver rack is far from the stage or behind walls and equipment. Mount the antennas on stands or walls with a clear line of sight to the performance area, and use quality low-loss coaxial cable to connect them to your receivers or antenna distribution system.

Setting Up Directional Antennas

Use two ADP UHF antennas for diversity receivers, spacing them apart and angling them toward the stage. Keep antennas above the audience’s heads for a clear line of sight, avoid placing them near metal structures, and keep cable runs as short as practical. When feeding multiple receivers, use an antenna splitter or distribution amplifier.

What to Pair With the ADP UHF

Pair the ADP UHF with Sennheiser EW-D wireless systems, low-loss BNC coaxial cables, antenna mounts or stands, and an antenna splitter for multi-channel racks. A second ADP UHF completes a diversity setup.

Why Upgrade Your Wireless Antennas?

Wireless problems are usually reception problems. Before replacing microphones or receivers, upgrading to directional antennas positioned correctly often solves dropouts and noise. It’s one of the most cost-effective improvements you can make to a church, theater, or venue wireless system, especially as more wireless devices compete for the same spectrum.

Sennheiser ADP UHF FAQ

Does the ADP UHF need power? No. It’s a passive antenna with no DC path.

Is it only for Sennheiser systems? It’s designed for Sennheiser EW-D and covers the 470-1075 MHz range, so it can be used with other UHF systems in that range that use BNC antenna connections.
