Description & Specification
900 MHz Precision Reference Antenna
Model: SL-900-V2 Series | 820 MHz - 980 MHz | CTIA Symmetry Compliant
The SL-900-V2 series provides a laboratory-grade Collinear Sleeve Dipole solution for mission-critical RF measurement. Engineered to deliver an exceptionally round radiation pattern with differences of less than 0.1dB, it is the definitive reference for Signal Defense gain calibration and chamber reflectivity evaluations. The 1/4 wavelength design and specialized sleeve isolate the radiator from cable interference, ensuring the precision required for CTIA ripple test compliance and professional antenna efficiency characterization.

Key Tactical & Engineering Features
CTIA Symmetry Precision
Meets the rigorous +/- 0.1 dB symmetry requirements, providing the high-level accuracy necessary for OTA chamber reflectivity evaluation and ripple tests.
Interference-Free Design
The 1/4 wavelength sleeve dipole architecture isolates the antenna from the feed cable, preventing pattern distortion and feedpoint contact issues.
Reference Grade Dominance
Serves as a reliable gain reference and low-gain efficiency standard for calibrating tactical UHF/GSM monitoring systems and electronic protection equipment.
Rugged Structural Integrity
Constructed with a premium fiberglass radome and PVC components, ensuring mechanical survival in both indoor lab and controlled outdoor environments.
