Figure 2 shows Z of Vertical Clip antenna for 145/435- MHz at 145- MHz band. Figure 3 shows SWR of Vertical Clip antenna for 145/435- MHz at 145- MHz band.

Figure 4 shows DD of Vertical Clip antenna for 145/435- MHz at 145- MHz band.

 

Figure 5 shows Z of Vertical Clip antenna for 145/435- MHz at 435- MHz band. Figure 6 shows SWR of Vertical Clip antenna for 145/435- MHz at 435- MHz band. Figure 7 shows DD of Vertical Clip antenna for 145/435- MHz at 435- MHz band.
