Below are described two broadband antennas for the 145- MHz. The antennas have low SWR at all 145- MHz Band also those ones are covered nearest parts of the frequencies to the 145- MHz Band. The antennas are easy to make and easy to tune.

 

Figure 1 shows design of the Crest Antenna for 145- MHz. The antenna has low SWR (less the 2.0:1.0) in the frequencies range from 135 up to 152- MHz. Figure 2 shows the impedance of the antenna in the working range. Figure 3 shows the SWR of the antenna. Figure 4 shows the DD of the antenna.

 

Figure 5 shows design of the Twin Delta Antenna for 145- MHz. The antenna has low SWR (less the 2.0:1.0) in the frequencies range from 139 up to 150- MHz. Figure 6 shows the impedance of the antenna in the working range. Figure 7 shows the SWR of the antenna. Figure 8 shows the DD of the antenna.
