Sennheiser ASP 113 Single Three-Way Passive Antenna Splitter

Passive three-way antenna splitter for sharing one antenna across three wireless receivers

The Sennheiser ASP 113 is a single three-way passive antenna splitter that divides one antenna signal into three outputs for feeding three wireless receivers from a shared antenna. Two ASP 113 units are required for a complete diversity setup, as each handles one antenna path. This provides a simple, unpowered antenna sharing solution for small wireless deployments where three receivers need to share a single antenna pair without the cost or complexity of an active antenna distribution system.

As a passive splitter, the ASP 113 introduces insertion loss on each output — the incoming signal is divided across three paths without amplification. This is acceptable for short cable runs and relatively close antenna-to-receiver distances. For longer cable runs or larger receiver counts, active splitters like the ASA series are recommended to compensate for the additional loss.

Key Features

• Three-way passive antenna splitting from a single antenna input
• No external power required
• BNC connections for standard wireless system cabling
• Compact form factor for simple rack or shelf deployment
• Two units needed for complete diversity receiver sharing
• Sold individually — two required for a full diversity pair

Professional Applications

Commonly deployed in church, house of worship, and professional AV environments.

• Small wireless systems with three receivers sharing one antenna pair
• Rental kits where simplicity and compact size are priorities
• Installations where active splitter power and cost are not justified
• Temporary or event wireless deployments with limited channel counts

Frequently Asked Questions

Why are two ASP 113 units required?

Diversity wireless receivers have two antenna inputs (A and B). Each ASP 113 splits one antenna path. Two units — one for antenna A and one for antenna B — provide the complete diversity distribution to all three receivers.

Can I cascade ASP 113 units for more than three receivers?

While physically possible, cascading passive splitters introduces compounding insertion loss that degrades signal quality. For more than three receivers, use an active antenna distribution system like the ASA series.

Related Equipment and Workflow Compatibility

The ASP 113 works with any Sennheiser wireless receiver with BNC antenna connections. For four-receiver sharing, see the ASP 114. For larger systems, use active ASA series splitters.

Why Professionals Use This Type of Product

• Simple, passive design shares antennas without power or configuration
• Compact size fits easily into small wireless racks and kits
• Cost-effective antenna sharing for three-receiver deployments
• No failure points — passive operation is inherently reliable
