SD 5650-A
➊ 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
➋ 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
➌ REPEATABILITY
• Stiff and robust mechanical design
• Minimum use of dielectric material
• Precision machined
• High reliability connector
