WISI Universal Antenna Outlet DB 03 D 2-Hole Single Outlet 5 dB SAT/TV/Radio

The WISI DB 03 D is a flush-mount universal antenna outlet engineered for modern in-wall installations where a single, clean connection point must serve satellite, terrestrial TV, and FM radio. Unlike basic outlets that only pass one band, this unit combines three dedicated outputs in a compact 2-hole design, with a defined 5 dB tap loss for balanced signal distribution in star-wired home networks. The die-cast metal chassis ensures long-term shielding stability, while the plastic cover blends into standard switch ranges.

Highlights

• Three independent outputs: SAT (F-connector), TV (IEC male), and Radio (IEC female)
• 5 dB attenuation (tap loss) for consistent signal levels across multiple outlets
• Full frequency coverage: 47–862 MHz (TV), 87.5–108 MHz (FM), 950–2200 MHz (SAT)
• Class A shielding per EN 50083-2 for interference-free reception
• DC passage on SAT output to power LNB or multiswitch
• Flush-mount installation with standard 2-hole spacing (60 mm)
• 75 Ohm impedance, return loss > 10 dB

In daily use

Installed behind a TV or in a media wall, the DB 03 D keeps cable runs tidy: one coaxial drop feeds the outlet, and the three front connectors let you connect a satellite receiver, a terrestrial TV, and an FM tuner simultaneously. The 5 dB tap loss is ideal for apartments or houses with multiple outlets, ensuring each room receives adequate signal without overloading the distribution amplifier. The SAT output passes DC, so no separate power inserter is needed for the LNB. The die-cast housing and snap-on cover withstand repeated plugging and cleaning without degrading shielding.
