Description & Specification
SL-800-SF-V2 UHF/LTE Precision Reference Antenna
UHF / LTE Reference Grade Radiator | CTIA Symmetry Compliant | 700 MHz – 900 MHz
The SL-800-SF-V2 provides a laboratory-standard Collinear Sleeve Dipole solution specifically engineered for high-precision OTA (Over-the-Air) performance validation and anechoic chamber calibration within the UHF/LTE spectrum. Covering the vital 700 MHz to 900 MHz frequency spectrum continuously, this premium reference radiator delivers an exceptionally round omnidirectional radiation pattern with a circular asymmetry profile of < 0.1 dB (up to 870 MHz) to ensure strict compliance with strict CTIA pattern symmetry requirements. Its specialized 1/4 wavelength structural sleeve balun completely isolates the feedpoint from cable-induced surface waves and cross-interference, guaranteeing the absolute Signal Integrity necessary for professional gain references, chamber reflectivity evaluations, and low-gain antenna efficiency characterization. Designed and manufactured in Taiwan, it represents the definitive evaluation standard for high-fidelity wireless test environments.

CTIA Ripple Test Precision
Engineered to satisfy rigorous ± 0.1 dB symmetry protocols, providing world-class electromechanical stability for OTA chamber reflectivity evaluation and advanced spatial ripple tests.
Interference-Free Sleeve Design
The 1/4 wavelength sleeve choke configuration effectively isolates the active copper radiator elements from the feed cable, entirely preventing pattern distortion and feedpoint contact scattering issues.
Taiwanese Engineering Excellence
Precision designed and manufactured by FT-RF in Taiwan under strict quality guidelines, ensuring structural concentricity, perfect axial leveling, and repeatable phase tracking factors.
Rugged Structural Integrity
Encased in a premium weather-resistant fiberglass radome shell with protective polymer accents, ensuring enduring lifespans across precision indoor laboratories and outdoor tactical field stations.
