Kathrein EXI 258 Filtro passa-alto para integração de multiswitch IP-coaxial 205500008

Integrating Kathrein IP-Coax devices with existing satellite and terrestrial multiswitch systems often creates frequency conflicts that degrade signal quality. The Kathrein EXI 258 high-pass filter solves this by cleanly separating the IP-Coax band (5-65 MHz) from the SAT/Terrestrial band (85-2200 MHz), allowing both to coexist on a single cable run without interference.

Who is it for

Installers and system integrators working with Kathrein IP-Coax equipment (such as EXI 01, EXI 02, EXI 04) who need to combine these signals with traditional SAT/TV distribution from a multiswitch. It is ideal for residential and commercial setups where both IP-based services and classic satellite/TV must share the same coaxial infrastructure.

Main features

• Separates IP-Coax (5-65 MHz) and SAT/Terrestrial (85-2200 MHz) frequency bands
• Low insertion loss (<1.5 dB) on both paths preserves signal strength
• High isolation (>30 dB) prevents cross-interference between bands
• DC pass-through on the SAT/Terrestrial path for LNB powering
• 75 Ohm impedance with three F-type connectors
• Die-cast housing for durability and shielding (>85 dB)

Specifications

• Frequency range IP-Coax: 5 - 65 MHz
• Frequency range SAT/Terr.: 85 - 2200 MHz
• Insertion loss IP-Coax: < 1.5 dB
• Insertion loss SAT/Terr.: < 1.5 dB
• Isolation IP-Coax to SAT/Terr.: > 30 dB
• Isolation SAT/Terr. to IP-Coax: > 30 dB
• Return loss: > 10 dB
• Impedance: 75 Ohm
• Connectors: 3x F-type
• DC pass-through: Yes (SAT/Terr. path)
• Shielding effectiveness: > 85 dB
• Operating temperature: -20 to +50 °C
• Housing: Die-cast

Tips

Install the EXI 258 close to the multiswitch to minimize cable losses on the IP-Coax path. Ensure all F-connectors are properly tightened to maintain shielding effectiveness and avoid signal leakage.
