Fitting a 2nd Aerial to a Spyder RT
To do this :-
Remove the speaker housing from the rear trunk, held by 3 screws on the inside
Disconnect the wires from the speakers - This will allow you to work with the speaker box
You now need to remove the outer painted cover from the inner cover - This is held by screws and some clips so once you remove the outer
cover you will need to pull out and slide the cover to split the speaker box
You will need the brass antenna holder in which the aerial will screw into
(This gives you the correct angle for the 2nd Antenna to match the other side)
The Antenna holder is held by a bolt and fits in the recess in the inner skin
Once you have fitted the Brass Antenna holder you need to put the Covers back together and reconnect the speaker wires
now just re-attach the speaker box to the rear trunk
The 2nd aerial is just screwed into the Brass Antenna holder and the job is done

Recess for Brass antenna holder to fit into (This is showing the side where the original aerial is fitted)
You will not have the Aerial wires fitted although you could fit a washer and a nut to the threaded screw which also helps to locate the brass
Antenna holder in that recess
Picture shows the balance an aerial on each side looks like
Hope this helps
