It is very simple antenna that allows works at several frequencies bands with low SWR. The antenna is enough broadband that does not required hold strictly sizes at the design. Figure 1 shows design of the antenna. Made according to the Figure 1 antenna does not require any tuning.

Figure 2 shows impedance of the antenna at the 2- meter Band. Figure 3 shows SWR of the antenna at the 2- meter Band. Figure 4 shows DD of the antenna at the 2- meter Band.

Figure 5 shows impedance of the antenna at the 70-cm Band. Figure 6 shows SWR of the antenna at the 70-cm Band. Figure 7 shows DD of the antenna at the 70-cm Band.
