Antenna Outlet Pass-Through WISI DB07D 5–2150 MHz 14 dB Universal 2-Hole Flush-Mount

The WISI DB07D pass-through antenna outlet is a flush-mount coaxial wall plate designed for distribution and testing of terrestrial TV, cable and satellite signals. It supports a wide frequency range of 5–2150 MHz and provides 14 dB attenuation to isolate connected equipment while maintaining a stable RF connection. The universal 2-hole connector fits standard wall boxes and offers a compact, standardized interface for residential and commercial installations where a durable, low-profile antenna outlet is required.

Advantages

The WISI DB07D combines a broad frequency range with fixed attenuation to simplify signal management across TV, cable and satellite services. Its flush-mount design reduces protrusion from the wall and the universal 2-hole fixing enables straightforward installation into common in-wall boxes. The device is built for reliability in everyday use, delivering consistent attenuation and a stable physical connection for test equipment and end-user devices.

Suitable for

• Residential wall outlets for terrestrial TV and cable distribution
• Commercial installations needing standardized flush-mount coaxial outlets
• Signal testing points in distribution networks where fixed attenuation is required
• Integrations with set-top boxes, modems or receivers that use F-type coax connectors

When it may not be suitable

Because the outlet provides a fixed 14 dB attenuation, it is not suitable where no attenuation or variable attenuation is required to achieve precise signal levels. It is intended for standard coaxial systems and may not fit proprietary connectors or non-standard wall boxes without appropriate adapters or frames.

Key specifications

• Frequency range: 5–2150 MHz
• Attenuation: 14 dB (fixed)
• Mounting style: Flush-mount / in-wall
• Connector type: Universal 2-hole coaxial outlet (standard F-type interface)
• Application: Terrestrial TV, cable and satellite signal distribution and testing

How to use

Install the WISI DB07D in a compatible in-wall box using the two standard fixing holes and secure the outlet flush with the wall surface. Connect the incoming coaxial feed to the rear inlet and attach the end device or test equipment to the front connector. Ensure coaxial cables and connectors are properly tightened and that cable shielding and grounding meet local installation standards. Use the outlet as a distribution or test point in the signal path where 14 dB attenuation is acceptable.

What to consider before purchase

• Required attenuation: confirm that a fixed 14 dB reduction suits your signal plan
• Wall box compatibility: verify the in-wall box supports a 2-hole flush-mount plate
• Connector compatibility: ensure connected devices use standard F-type coaxial connectors
• System grounding and shielding requirements for your installation

Usage recommendations

For stable long-term performance, use quality coaxial cables and connectors, check signal levels before and after installation, and comply with local grounding standards. If precise level adjustment is needed, consider adding an inline attenuator or an adjustable attenuation element elsewhere in the distribution network rather than relying on a fixed outlet.
