6.17.  Aerials
6.17.1. Radio receiving and transmitting aerials shall be fitted to the vehicle in such a way that if their unattached end is less than 2 m from the road surface in any position of use specified by the manufacturer of the aerial, it shall be inside the zone bounded by the vertical planes which are 10 cm inside the extreme outer edge of the vehicle as defined in paragraph 2.7. of this Regulation.
6.17.2. Furthermore, aerials shall be so fitted to the vehicle, and if necessary their unattached ends so restricted, that no part of the aerials protrude beyond the extreme outer edge of the vehicle as defined in paragraph 2.7. of this Regulation.
6.17.3. Shafts of aerials may have radii of curvature of less than 2.5 mm.  However, the unattached ends shall be fitted with fixed cappings, the radii of curvature of which are not less than 2.5 mm.
6.17.4. The bases of aerials shall not project more than 40 mm when determined according to the procedure of paragraph 2. of Annex 3 to this Regulation.
6.17.4.1. In cases where by the absence of a flexible shaft or part it is not possible to identify what the base is of an aerial this requirement is deemed to be met if, after a horizontal force of not more than 50 daN in forward and rearward direction is applied by a flat-ended ram of not more than 50 mm diameter at the most salient part of the aerial:
                  (a) The aerial bends towards the support and does not project more than 40 mm, or
                  (b) The aerial breaks off and the remaining part of the aerial does not show any sharp or dangerous part that can be contacted by the 100 mm sphere and does not project more than 40 mm.
6.17.4.2. Paragraphs 6.17.4. and 6.17.4.1. above shall not apply to aerials located behind the vertical transversal plane passing through the "R" point of the driver, provided that the maximum projection of the aerial including its housing does not exceed 70 mm when determined according to the procedure of paragraph 2. of Annex 3 to this Regulation.
If the aerial is located behind that vertical plane but projects more than 70 mm, paragraph 6.17.4.1. above shall apply using a projection limit of 70 mm instead of 40 mm.
6.18.  Assembly instructions
6.18.1. Luggage racks, ski racks and radio receiving or transmitting aerials that have been approved as separate technical units may not be offered for sale, sold or purchased unless accompanied by assembly instructions.  The assembly instructions shall contain sufficient information to enable the approved components to be mounted on the vehicle in a manner that complies with the
