OPTICUM 1x4 DVB-T/SAT signaalinjakaja 5-2400 MHz F-tyyppi sinkkipainevalu

In a multi-room home or small apartment, distributing a single antenna feed to four TVs or set-top boxes often requires a reliable splitter that handles both terrestrial and satellite bands. The OPTICUM ANT0043 is a 1-input, 4-output signal splitter built for exactly that scenario. It accepts one coaxial input from a DVB-T antenna or SAT LNB and splits it to four outputs, enabling simultaneous reception on multiple devices without signal degradation beyond expected splitting loss.

Key specifications

• Product type: Signal splitter
• Input ports: 1
• Output ports: 4
• Frequency range: 5 - 2400 MHz (covers DVB-T: 5-862 MHz and SAT: 950-2400 MHz)
• Insertion loss: approx. 8.5 dB (5-862 MHz), approx. 9.5 dB (950-2400 MHz)
• Isolation between outputs: >20 dB (5-862 MHz), >18 dB (950-2400 MHz)
• Return loss: >12 dB (5-862 MHz), >10 dB (950-2400 MHz)
• DC pass: Yes, from one output (OUT1) to input for remote powering of preamplifiers or LNBs
• Impedance: 75 Ohm
• Connector type: F-type female
• Shielding class: A
• Housing material: Zinc die-cast
• Application: Indoor
• Mounting: Screw mountable

Why choose it

The zinc die-cast housing provides excellent shielding against electromagnetic interference, ensuring clean signal distribution even in environments with multiple electronic devices. The wide frequency range means you can use a single splitter for both terrestrial TV (DVB-T) and satellite (SAT) signals, reducing the need for separate components. DC pass-through on one port allows you to power an active antenna or LNB directly through the coaxial cable, simplifying installation.

Ideal use cases

• Distributing a rooftop DVB-T antenna signal to four TVs in different rooms.
• Splitting a satellite LNB output to multiple receivers in a home or small office.
• Combining terrestrial and satellite signals in a single distribution system.
• Indoor installations where a compact, screw-mountable splitter is needed.

Good to know

The splitter is designed for indoor use only. Ensure all unused outputs are terminated with 75-ohm caps to maintain signal integrity. The DC pass function is limited to one specific output (typically marked OUT1); check the label before connecting a power inserter. Installation is straightforward: connect the input cable to the IN port, then connect up to four output cables to your devices. The splitter can be mounted on a wall or inside a distribution box using the screw holes on the housing.
