I don't have the measurements so can't say for certain, but everything I have seen shows them appearing to be no higher than the monorail at most point. Especialyl considering they are hanging down (so lower than the cable) for the monorail on top (so higher than the beams)
Here is a photo of them testing with the work gondolas over the parking lot
vs the monorail - this is by the Contemporary which I think is the highest the monorail gets, but it appears at least at this point to be higher than the Skyliner will be
