Winegard RV-7042 Wall Plate Power Supply

The Winegard RV-7042 White Wall Plate Power Supply is the interior power and control module that runs your RV antenna lift and rotation for reliable over-the-air HDTV reception.

Included as part of a complete Winegard RV antenna system, the RV-7042 wall plate supplies power to the roof antenna's motor and provides a convenient inside control point. It pairs with Winegard crank-up antenna assemblies to let you raise, lower, and rotate the antenna from within your rig, while supporting long-range VHF/UHF reception for free local channels. Built for mobile use, this unit fits standard wall plate cutouts and integrates with the antenna's wiring so installation is tidy and accessible.

How does the RV-7042 power supply make using an RV antenna easier?

The RV-7042 centralizes power and control at an indoor wall plate so you can operate the antenna without climbing to the roof. Its placement near your TV or entertainment center keeps cables short and eliminates the need to access the roof for daily adjustments. The unit also protects the control interface and electrical connections from the elements.

• Mounted inside the RV for convenient reach and safe operation.
• Delivers stable DC power to motorized lift and rotation systems.
• Simple wiring connects antenna head, motor, and coax runs.
• Compatible with Winegard crank-up antenna assemblies and kits.

What reception improvements can I expect with this system?

When combined with a Winegard long-range VHF/UHF antenna, the powered system increases the chance of pulling in distant 4K/HD broadcasts and local stations without subscription fees. Rotational control lets you aim the antenna toward the strongest transmitter, while the antenna’s rugged design maintains stable performance while traveling. Results depend on terrain, distance to transmitters, and obstructions.

• Supports over-the-air local HDTV including news, sports, and primetime.
• Rotation capability helps optimize signal for multiple transmitter directions.
• Engineered for VHF/UHF to access a wider range of channels.

How durable and RV-ready is the RV-7042 power supply?

The RV-7042 is part of a system built specifically for mobile use, pairing with hardware designed to withstand wind, vibration, and changing weather conditions. The internal electronics are housed behind a protective wall plate to reduce exposure to dust and moisture. Use with the matching Winegard antenna kit ensures components mate correctly and operate reliably on the road.

• Wall plate mounting protects controls from outdoor elements.
• Designed to integrate with rugged antenna heads and lift mechanisms.
• Engineered to tolerate RV motion and frequent setup cycles.

What does the complete kit include and how simple is installation?

The Winegard RV antenna kit that uses the RV-7042 typically ships with the antenna head, the lift and rotation mechanism, the interior wall plate power supply, and all necessary hardware for mounting. Installation involves roof and interior wiring, securing the lift mechanism to the roof, and connecting the wall plate to the antenna motor and coax. If you prefer, professional installation services are commonly available.

• Includes antenna head, lift/rotation assembly, wall plate power supply, and mounting hardware.
• Requires roof penetration for mounting and coax cable routing inside the RV.
