KATHREIN EMU 290 antennekoppelaar F-stekker galvanische scheiding DC-blocker

Galvanic isolator with F-connectors that blocks DC voltage and low-frequency interference while passing satellite, terrestrial and cable TV signals from 5 to 2400 MHz. Prevents hum loops and potential equalization currents in antenna systems.

Advantages

Nickel-plated brass housing provides high shielding effectiveness and durability. Inline male-to-male F-plug design installs directly between antenna cable and receiver without additional adapters.

Suitable for

• Satellite reception (DVB-S/S2)
• Terrestrial TV (DVB-T/T2)
• Cable TV (DVB-C)
• Eliminating ground loop hum in AV setups

Key specifications

• Frequency range: 5–2400 MHz
• Impedance: 75 Ohm
• Insertion loss: < 1.0 dB
• DC isolation voltage: > 2.5 kV RMS
• Return loss: > 18 dB
• Shielding effectiveness: > 100 dB
• Operating temperature: -20 to +50 °C

Recommendations

Install the EMU 290 directly at the receiver input or antenna wall outlet. For best signal quality, ensure all F-connectors are tightened securely and use high-quality coaxial cable rated for the required frequency range.
