The simple antenna effectively works for 145 and 50- MHz. It is a symmetrical antenna. However, unsymmetrical version of the antenna is still working. For the antenna ground should be used good conductivity surface or several resonance counterpoises for each band.

Figure 1 shows design of the antenna.

Figure 2 shows Z of the antenna on the 50- MHz Band. Figure 3 shows SWR of the antenna on the 50- MHz Band. Figure 4 shows DD of the antenna on the 50- MHz Band.

Figure 5 shows Z of the antenna on the 145- MHz Band. Figure 6 shows SWR of the antenna on the 145- MHz Band. Figure 7 shows DD of the antenna on the 145- MHz Band.
