Thanks Radio!

Initially, with rhe radials straight, the antenna was resonant at 154.000 mHz with a SWR of 2:1. I freq'ed out and soldered a 6" extension on to the vertical and bent the radials to 45°the based on your advice. Then I ended up trimming the vertical radiator back to the original length and achieved a resonant frequency of 146.000 mHz with a SWR of 1.5:1 at 50 Ohms. Just for the sake of experiment, I rotated the radials 1/4 turn, reducing the angle to about 22.5° which resulted in a SWR of 1.2:1 @50 50 Ohms.
