Over the past couple of weeks I have added radials to the antenna bringing the total to 18; each one is 136 feet in length. The following plots were generated using the (WX0B) AIM-4170 antenna analyzer and they show a wide view of the antenna -- in terms of the (scale) of the plot and then one that presents a more detailed in-band plot.
The wide view of the antenna with the red line showing SWR and the green line showing impedance.
This more detailed plot shows a little more detail
