1 GHz Directional Taps/Couplers
CMCDT2100 Series
The CMCDT2100 Series Directional Taps provide users with a variety of
installation options. The L-type housing is perfect for in-wall installations where
dimensions have been minimized by removing the mounting tabs. The T-type
housing includes a mounting tab. Both styles are SCTE compliant.
The Antronix CMCDT2100 Series directional taps have been designed with
today’s two-way broadband networks in mind. Our proprietary ferrites resist
re-magnitization and remain ultra linear for consistent performance throughout
its lifetime.
Additionally, our directional couplers are among the most robust in the
industry. Every port on each directional coupler is 6 kV ring wave protected.
To ensure years of reliable operation, the couplers are encased in a Zinc Alloy
diecast housing, plated with a proprietary Nickel Alloy which provides superior
protection versus tin-plating. Each port is sealed to 15 psi to prevent water
migration and meets SCTE specifications.
• 6 kV Ring Wave Surge Protected •

All ports are protected against multiple 6 kV ring wave surges per IEEE specification C62.41 Category A3.
Excellent Distortion Performance
Proprietary ferrite blend inhibits re-magnetization of the core due to voltage spikes from impulse noise or lightning.
The ferrite remains ultra-linear to prevent intermodulation where high level return carriers can affect forward path
video signals.
Digital Broadcast and HDTV Ready
Compatible with existing and future networks such as VoIP and DOCSIS 3.0.
Flat 1 GHz Bandwidth with Minimal Insertion Loss
Supports present and future multimedia applications including voice, video and data.
Capacitively Coupled F-Ports
Protects against core re-magnetization and saturation while blocking AC surges.
Zinc Alloy Diecast Housing and Backplate w/Proprietary Nickel Alloy Plating
Superior corrosion resistant plating combined with a diecast backplate protects the back of the housing where
corrosion is more prominent.
100% Soldered Back
Ensures reliable & repeatable 120 dB RFI shielding.
Flat 15 psi Sealed, SCTE Compliant F-Ports Prevents water migration, while meeting SCTE standards.
• UV Resistant Label
• Integrated Mounting Tabs
The T-type housing incorporates the mounting tab.
• 75Ω Nominal Impedance
