Yes, it replaces the first 1/4 turn all together. Attach your coil to the insdie of that tube instead of the top. Also, the end of your first turn should end at 2-1/8" above the ground plane. Thus the first turn spacing will be a little off due to the conductor being parallel rather than tapered. Just be certain that it ends at the right place.

I will do some experimenting with a more easily repaetable match that maintains the coil integrity through the first turn. The tapered match works, but is hard to get perfect.
