all you have to do is this
1) unscrew Antenna from the base unit!
2) Attach new antenna cord to the base of Antenna with screw already provided.
3) now this is tricky and I did mine by eyesight w/o tape to make lines.
Center the new sharkfin over the base antenna and remove protective tape. Center and push down firmly all the way around
4) VOILA you are done and have installed your new sharkfin antenna!!


COOOOOOOLLLLLLLLLLLLL!!!!!!!!!!!!!!!!!!!
