Protects mounts when antenna is taken offFits all NMO mountsBlack heavy-duty plasticO-ring type gasket
Those appear to be NMO mounts from the photo. Very standard. Amazon has lots of caps for NMO mounts for just a few bucks, or you could also just get some antennas to put on them. Alternatively, Amazon also sells NMO rubber gaskets which will seal them so they don't leak anymore.
Same here:

The white and black cylindrical low profile antennae, and the two whips are NMO mounted. You should be able to carefully unscrew them to reveal the mount, which will be about 1/4" in height. The holes drilled for these mounts can vary between 3/8"-3/4". There should be no leaks if you leave the mounts installed. This should clear the roof enough for solar.
Replace the antennae with these suckers: https://www.amazon.com/Tram-1290-Nmo-Rain-Cap/dp/B00474A1M2
As for the shark fin... I'd leave that one for style points!
