The Johansson 4503 is a 3-way wideband splitter designed for indoor use in satellite and terrestrial TV distribution systems. Its wide frequency range of 5–2340 MHz makes it compatible with wideband LNB systems, and DC pass is provided on all three ports with diode protection, allowing LNB power to pass through from the receiver without the need for a separate power inserter on each branch.

The housing is manufactured from nickel-plated zinc diecast, providing both RF shielding and mechanical durability. All connections are made via standard "F"-type connectors. This product is supplied as a pack of 50 units.

Key Features

• 3-way wideband splitter
• Frequency range: 5–2340 MHz
• DC power pass on all ports (with diode protection)
