Figure 154 SWR for Buddipole vertical with L-radial on 20m at 16 feet Again, even at 16 feet this is a very difficult antenna to match to 50 ohms. Though the height may be satisfactory for an antenna design like this, the element lengths are simply too short for this band. A similarly designed antenna with longer whips is discussed later and the longer element lengths make a big difference. The far-field plot for this antenna over good ground appears below.
