OMNIDIRECTIONAL REFERENCE CALIBRATION ANTENNAS

Precision Sleeve Dipole Antennas (SL)

The SL Series Precision Sleeve Dipole Antennas are high-precision omnidirectional reference antennas engineered for range calibration, site attenuation verification, and wireless device testing. Featuring an advanced end-fed sleeve dipole architecture, these antennas isolate the feeding coaxial cable to eliminate cable and feed point reflections that typically degrade radiation symmetry and measurement accuracy.

Each SL Series antenna exhibits a standard 50 Ω nominal impedance, an electric dipole pattern that closely matches a theoretical half-wave resonant dipole, and individual calibration data including Gain, VSWR, maximum ripple, and measurement uncertainty values.

*Custom frequency bands, low-loss cable integration, and individual calibration certificates are available upon request.
