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
