Roof Antenna Installation (I No. 461)

Vehicle Type:
911 Carrera (997)7911 Carrera S (997)

Model Year:
As of 2005

Filing:
This bulletin replaces bulletin Group 9, #5/05, dated 5-24-05.

Situation:
Retrofitting

Concerns:
ONLY Coupe

NOTE:



An external antenna can be retrofitted on the roof of the vehicles specified above for improved AM reception. In this case, one of the two ultra-short wave antennas on the windshield (antenna diversity) is no longer needed.

The standard electric wire harness for the external antenna is included in the scope of delivery.

Only the antenna wire (HF line) for the external antenna/antenna diversity control unit and the power supply line for the external antenna/PCM are required for subsequent installation. These must be disconnected from the standard wire harness. The other wires will not be needed.

NOTE: Measure the marking again before drilling.




2.2 Mark the drilling position on the adhesive tape (see dimensions below).

Dimension "X" = approx. 455.00 mm, centered with respect to the roof width;

Dimension "Y" = 42.5 mm from edge of rear-window roof seam

2.3 Drill a hole at the point of intersection of the marked lines using a steel drill bit (diameter =2 mm) and drill it out to a diameter of 19 mm using a paring drill bit.
