Yes, with aftermarket radios you can use only one or the other. The dual antennas are a diversified antenna that switches between one or the other depending on reception. The stock deck determines this, thus aftermarket radios can only use either. If you hook up both antennas you could get unwanted multipath.93LegendCoupe said:Sorry guys stupid question, but I'm a newbie.... is this part intended to make BOTH the window and regular antenna work simutaniously or is it just for the window antenna? basically what i'm asking is that if you install this part and use the window antenna, do you lose the use of your regular antenna? also, does that part work w/ all aftermarket radios?
Look closely at your ack window. You will notice there are a couple lines above the rear window glass defrester that is NOT connected to the rest of the lines. This is your window antenna. The cable plug to hook it up is located right behind your deck near your mast antenna plug.Sprung17 said:So where is this back window antenna located at? Where is the cable used to hook up to the radio?
