SD 5650-A
TECHNICAL PERFORMANCE
Low loss and high effi ciency
Azimuth pattern symmetry is within ± 0.1 dB
variation as specifi ed by the CTIA for ripple testing according to the OTA Test Plan
DESIGN
End-fed sleeve dipole technology, minimizing
cable and feed point interaction
Innovative choke design further reduces cable
interaction by attenuating the natural return currents from the dipole
Azimuth pattern symmetry thanks to entirely
symmetrical design
REPEATABILITY
Stiff and robust mechanical design
Minimum use of dielectric material
Precision machined
High reliability connector
