I placed a corrugated tube in the most forward part of the VS, from bottom to top. It was secured at top and bottom with tie-wraps (made two little holes for this in each location).
Then, I run inside the tube the coax cable for VOR antenna. I did the two operation at the same time, AFTER completion of VS. It is not difficult. I must add that I have a removable VS tip.
One end of the corrugated tube extends a few inches far from the bottom of the VS. This allows for it to enter slightly in the tail cone, when the VS is assembled to the fuselage.
You can do the same.
Apart from this, I believe you can place the strobe inside the rudder fairing, as most do and as I did.
Ciao.
