Title for EXTREME BROADBAND Splitter BDS103H

Image Antronix CMC2003H Broadband 3-way unbalnced splitter


Standard broadband cable TV splitters have an operational bandwidth from 5-1002Mhz. The Modem return band enhansed performance in the 5-30MHz frequency spectrum.

Round center conductor siezing pins with white insulators contained in the SCTE compliant F ports

Center conductor seizing surface is greater than other device's surroundiing contact area. Providing long term trouble free signal transfer between the coaxial connector and the splice adapter.

Nickel-plated, zinc die-cast housing with soldered back plate provides -130dB of RFI integerty. All f ports are
highly precision machined with SCTE compliant threading and are spaced on 1" centers.

All ports are protected to survive up to 6kV ring wave overvoltage events.

All ports are enviromntal sealed and to withstand 15 psi of internal pressure. All ports are flat topped to increase the ground and interface seal comply to all existing SCTE standards.

High return loss (VSWR) across entire ops. Allow reduced reflections when digital signals are transported.

Built-in NPO capacitors on all ports. All components are temperature hardened. Devices designed to remain stable in enviroments of -40 to +85o C and maintain all technical specifications.

Non-memory retaining beryllium copper center conductor CAMPORT™ seizing pin holds fast to coaxial center conductor.

Flat F end ports, provides excellent mating plane surface for proper grounding between the F connect and the device.

The device does not transmit or handle AC or DC powering or DSS Satellite signals. Application of AC/DC voltages to the device will render the device non-operative and will void the warranty


The Antronix CMC2003H series broadband splitter has been specifically designed to be fully compliant to the requirments of D3 (DOCSIS 3.0) & D2 (DOCSIS 2.1) Cable modem operatios.

The device splits signal with (2) two balanced loss outputs and (1) one output with 2.0dB less loss. The device distributes CATV and OTA HDTV video to up to three (3) devices. .
