Radars on the USS Enterprise mast

Another insane detail question - I'm updating the USS Enterprise to her 2006 appearance, important because the model is for a person currently deployed on her. I've got two of the radars puzzled out, the SPS-48 on top of the island, forward, and the SPS-49 at the same level aft. What's defeating me are the radars on the mast. There appear to be at least three:

• One on the forward side of the mast, at the lower crosstrees. An SPS-10?
• One on the aft side of the mast, below the lower crosstrees. This one has me stumped, but I'm guessing SPS-12?
• One on the aft side of the mast, at the upper crosstrees. Some kind of navigation radar?

As usual, any help would be appreciated. I'm not an electronics guy, most of the WW II cargo ships I've built had none of those fancy doo-dads.
