Fixing the cluster of an stereo install I inherited with my truck and I see that there is two antenna connectors (which I believe is referred to as the diversity system). Only one of the connectors had been hooked up and my question is, do I need both? I have found a round about way of connecting the two into a standard DIN connector, but I don't want to buy the parts if it wont work or if it won't make a difference.
Diversity (dual) Antenna: Do I need both?

well, according to lr, it has "diversy tunning" one antenna fitted to each side of the vehicle so as vehicle turns it does not loose frequency signal, it diversifies the signal. being aluminum body it does not ground well for a regular stick antenna.
that being said the reception on an aftermarket head unit will never be the same as factory, does not matter if you use on or both antennas. btw to use both you need a "Y" joint or splitter https://www.ebay.com/itm/322845501546 as well as https://www.crutchfield.com/p_12040VW12/Metra-40-VW12-Antenna-Adapter.html?tp=2569

Right, I just didn't know if using both would be advantageous. I guess I can hook it up with the one and see if it gets the job done. I actually don't listen to the radio that often so it probably doesn't matter, I just like to know these things. I'll try that and report my findings.

Something to remember about the diversity system is that one antenna is AM/FM, the other is FM only. AM does not need a back up for clarity since "AM stereo" was a huge flop. FM easily looses clarity thus the diversity system came about to solve signal drops. So when installing an aftermarket kit, use both since you have them.
