Sirius with FM Direct Adapter

[Malibu Jim]

Looking at connecting my Sirius unit to my radio with a FM Direct Adapter. I think I need adapters between the adapter box and radio/antenna. Some adapters say the adapter will void the "diversity function." What is the diversity function?

Diversity function is this:

If your infiniti has 2 antennas (like my I35) it'll pick the signal from the antenna that has less interference on it.

If you're in a major metropolitan area, it won't be that big of a loss.
