This procedure covers the removal and replacement of the roof-mounted antenna assembly on a 2011-2014 Ford F-150, including disconnecting the antenna cable and installing a new antenna mast or base.

Warnings

Tools required

Parts

• Roof antenna assembly × 1 — Use OEM specification
• Antenna gasket/seal × 1 — Usually included with antenna assembly

Preparation

1. Park vehicle on level surface and ensure roof is clean and dry
2. Open rear door on driver's side for easier headliner access
3. Gather all tools and new antenna assembly
4. Verify replacement antenna matches original configuration

Procedure

1. 1

   Access interior overhead console area
   From inside the cab, locate the overhead console near the rear of the headliner. Carefully pull down the rear edge of the headliner approximately 2-3 inches to expose the antenna cable routing. Use caution not to bend or crease the headliner material.
2. 2

   Disconnect antenna cable
   Locate the antenna cable connector attached to the base of the antenna assembly. The connector is typically a push-on style coaxial connector. Firmly grasp the connector and pull straight down to disconnect it from the antenna base. Do not pull on the cable itself, only the connector body.
3. 3

   Access exterior antenna mounting
   Exit the vehicle and use a step stool or ladder to safely access the roof. Locate the antenna mast on the rear section of the roof, typically positioned on the driver's side near the center.
4. 4

   Remove antenna mast
   Grasp the antenna mast firmly and rotate counterclockwise to unthread it from the antenna base. The mast should unscrew by hand. If replacing only the mast, proceed to reinstallation. If replacing the entire base assembly, continue to next step.
5. 5

   Remove antenna base mounting bolts
   Using a 10mm socket, remove the mounting bolts securing the antenna base to the roof. There are typically 3-4 bolts in a circular pattern around the base. Keep track of any washers or spacers under the bolt heads.

   Module Mounting Bolts8 Nm (6 lb-ft)
6. 6

   Remove antenna base assembly
   Carefully lift the antenna base assembly straight up from the roof opening. The previously disconnected cable should feed through the roof opening freely. If resistance is felt, verify the cable is fully disconnected inside the cab and not snagged on any roof structure.
7. 7

   Inspect and clean mounting surface
   Inspect the roof opening and mounting surface for rust, debris, or damage. Clean the mounting surface thoroughly with shop towels. Check the condition of the existing gasket/seal and remove any old adhesive or gasket material if necessary.
8. 8

   Install new antenna base gasket
   Position the new gasket or seal onto the antenna base assembly, ensuring it seats properly in the gasket groove. Verify the gasket is correctly oriented to match the roof contour and mounting hole pattern.
9. 9

   Feed cable and position new base
   From outside the vehicle, feed the new antenna cable down through the roof opening. Have an assistant inside the cab guide the cable to prevent kinking. Position the antenna base over the mounting holes, ensuring the gasket seals properly against the roof surface.
10. 10

    Install and torque mounting bolts
    Install the mounting bolts with any washers or spacers in their original positions. Thread bolts by hand first to prevent cross-threading. Torque bolts in a cross-pattern to 31.0 Nm (23 lb-ft) to ensure even gasket compression and prevent water leaks.

11. 11

    Connect antenna cable
    From inside the cab, locate the antenna cable connector and firmly push it onto the antenna base connector until it clicks or seats fully. Ensure the connection is secure by gently tugging on the connector body.
12. 12

    Install antenna mast
    Thread the antenna mast clockwise into the antenna base by hand. Tighten firmly by hand only; do not use tools as this may damage the threads. The mast should thread in smoothly without excessive force.

Reassembly

1. Carefully return the headliner to its original position, ensuring no wrinkles or damage
2. Verify all interior trim pieces are properly seated
3. Clean any fingerprints or marks from the exterior antenna and roof area

Verification

• Turn the ignition to ACC or ON position and verify radio reception on AM and FM bands
• Test multiple radio stations across different frequencies to ensure proper signal strength
• Inspect the antenna base exterior seal for proper seating with no gaps
• Check for water leaks around the antenna base after the next car wash or rain
• Verify the antenna mast is secure and does not wobble excessively
