Description & Specification
UMTS/LTE Precision Reference Antenna
Model: SL-2145-SF | 1995 MHz - 2295 MHz | CTIA Symmetry Compliant
The SL-2145-SF is a high-performance Collinear Sleeve Dipole radiator specifically engineered for anechoic chamber calibration and OTA testing. Featuring an ultra-precise radiation pattern with roundness differences of less than 0.1dB throughout its bandwidth, it serves as the definitive reference for Signal Defense gain measurements. The 1/4 wavelength design and specialized sleeve isolate the feed point from cable contacts, ensuring the Signal Integrity required for mission-critical CTIA ripple test measurements and professional antenna efficiency characterization.

Key Tactical & Lab Features
CTIA Ripple Test Precision
Engineered to meet strict +/- 0.1 dB symmetry standards, providing the high-level accuracy necessary for OTA chamber reflectivity evaluation.
Interference-Free Architecture
The 1/4 wavelength sleeve dipole design isolates the antenna from the feed cable, preventing pattern distortion and feedpoint interference.
Reference Grade Dominance
Serves as a reliable gain reference and low-gain efficiency standard for calibrating high-frequency monitoring sub-systems.
Compact Structural Integrity
Encased in a premium fiberglass radome with a lightweight build, suitable for high-precision indoor lab and controlled outdoor environments.
