Window Feed-Through Antenna Connector Opticum 7440 F-F — pass-through F-type coaxial connector for window installation

Opticum 7440 is a window feed-through antenna connector with F-type female-to-female coupling designed to allow a coaxial antenna cable to pass through a closed window or thin wall without drilling. The connector maintains shielding continuity and a stable F-type connection between indoor and outdoor coax runs, enabling television and satellite installations where permanent wall penetrations are not desirable. Its compact design fits between window panes or in narrow gaps and provides a weather-resistant interface for short-term or semi-permanent cable routing.

Advantages

The pass-through F-type connector preserves cable shielding and minimizes signal loss at the connection point while eliminating the need for wall drilling. Its female-to-female coupling simplifies connection of two F-type coax leads and supports standard TV and satellite cables. The compact, low-profile construction reduces visibility and fits most typical window gaps, making indoor/outdoor cable routing straightforward and reversible. The connector is compatible with common coaxial cable diameters and is suitable for temporary or rental installations.

Suitable for

• Routing TV or satellite coaxial cable through closed windows and balcony doors
• Temporary antenna installations in rented apartments or houses
• Avoiding drilling when installing external antennas or amplifiers
• Maintaining shielding continuity between indoor and outdoor cable runs

Key specifications

• Connector type: F-type female-to-female pass-through
• Compatibility: standard 75 Ω coaxial TV and satellite cables
• Design: low-profile, suitable for window or narrow gap installation
• Material: metal contact surfaces with insulating housing for secure connection
• Function: maintains shielding continuity and provides a sealed connection when fitted in a gap

How to use

Place the Opticum pass-through connector in the window gap so the female coupler is accessible on both sides of the closed window or door. Feed the outdoor coaxial cable into the outer side of the connector and attach the indoor cable to the inner side, screwing both F-type connectors by hand until secure. Ensure the cable centres are correctly engaged and that the connector sits stably in the gap to avoid pinching the cable when the window is closed. Check signal quality on the TV or receiver after connection and tighten slightly if necessary; avoid overtightening metal parts by hand.

Usage recommendations

For best results, use standard 75 Ω coaxial cables with properly prepared ends and verify that the window gap or sash width is sufficient to accommodate the low-profile connector without compressing the cable. For long-term outdoor exposure, protect exposed cable sections and connector interfaces from direct weather using appropriate sealing or cable management; avoid forcing the connector into overly tight gaps to prevent damage to the cable or window seals.
