You did an excellent job with your antenna, now just get it up in the air!

I would make the rotor coax loop as close to the antenna feed point as possible.

I use a dual ferrite 1:1 choke balun box which is much better than an air wound coil balun and have the box mounted to the mast above the rotor. Then I use a piece of RG 213 coax for the rotor loop to the antenna feed point. RG213 is an excellent choice for a short rotor loop cable because it is stiff enough where it won't flop in the wind putting stress on the coax connector, yet flexible enough to bend while the rotor turns.

Here's 2 pics of my antennas (old setup with a Maco 103c and my current Mosley MP-33 NW ) where you can see the RG213 coax cable coming out of a choke balun box to the antenna feed point with plenty of slack for turning the rotor.
