The SL-700-SF is a laboratory-standard Precision Sleeve Dipole Reference Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for high-precision UHF band microwave measurements and system calibration routines. Operating continuously across the 600 MHz to 800 MHz frequency spectrum, this premium omni-directional antenna features an optimized sleeve balun geometry that completely decouples the radiating element from feed-cable currents, delivering an exceptionally clean radiation field. It is rigorously calibrated to meet the strict CTIA ±0.1 dB pattern symmetry thresholds, making it an indispensable standard for Over-the-Air (OTA) chamber reflectivity evaluations and ripple test characterization. Meticulously manufactured in Taiwan from structural fiberglass and high-grade aluminum, this robust 23 x 324 mm dipoled structure maintains its tuning profile under continuous continuous-wave power loads up to 150 Watts (CW). Equipped with a standard premium SMA-Female port, it serves as the definitive reference master for commercial wireless compliance, defense monitoring calibration, and traceable laboratory efficiency benchmarks.
