I took a few pictures today during my install of the TRD Roof Fin/Antenna.
The installation was quite easy. Here are some step by step instructions with pictures.
1. Unscrew OEM antenna from base.
2. Clean roof area where the antenna is to be installed.
3. Place the provided grid from TRD over the antenna base and tape down. I used painters tape to hold it in place.
4. Once in place remove the middle section(B) from the outside section(A). Then place the roof fin in the removed section of the grid. After I placed the roof fin in the area, I adjusted the tape(one corner at a time) to ensure that the roof fin was not overlapping the grid.
5. Once you are satisfied with the placement, place the roof fin on it's side. Then attach the wire antenna to the base with the supplied screw and washer.
6. Double check your placement to ensure nothing has changed. Remove the film from the double sided tape. Line up roof fin with the grid and press down firmly. Make sure to even amounts of pressure when pressing the roof fin against the roof.
7. Remove grid and enjoy!
