Antennas DDRR in military communication


Antennas DDRR are used in military communication of many countries. Figure 4 shows the schematic of antenna DDRR. Say simple the antenna represents a tube bent in shape of letter "L".




The length of the "L" is little smaller the quarter wave of the high lower operation range of the antenna, but the length 'L' not less the 0,1l at lower operation range of the antenna.
