CM
CM  ELEMENT DATA (all dimensions in meters):
CM    Reflector:  L = 0.667 m  pos Y = -0.270 m
CM    Driven:     L = 0.641 m  pos Y =  0.000 m
CM    Director 1: L = 0.606 m  pos Y = +0.338 m
CM    Director 2: L = 0.589 m  pos Y = +0.675 m
CM    Director 3: L = 0.575 m  pos Y = +1.080 m
CM
CM  ELEMENT DIAMETER: 6.35 mm (1/4 in. aluminum rod)
CM  BOOM HEIGHT AGL:  5.0 m
CM  EXPECTED GAIN:    9.2 dBd (11.35 dBi)
CM  EXPECTED F/B:     22 dB
