 Pix of R230 SL antenna mod
Using Gauge 30 insulated wire, 75 cm each (I only had one color wire), below is a photo of the two wires soldered but not wound: 
Next, testing on the car before winding the wire, the range with the SmartKey is close to the R170 mod but maybe 15 ft less range. 
Gauge 30 wire after winding the wire. The winding of the wire is done with the antenna not connected to the car. I tested it again before putting on the antenna cover.
