Description & Specification
SL-82M1G-SF Precision Sleeve Dipole Antenna
High-Precision Reference Dipole | 820 - 980 MHz | Model: SL-82M1G-SF
The SL-82M1G-SF is a precision sleeve dipole antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) in Taiwan. Operating across the 820 MHz to 980 MHz spectrum (up to 1 GHz), it delivers a stable gain of 0.9 to 1.65 dBi along with an exceptional radiation efficiency of 92% to 98%. Specifically compliant with CTIA specifications featuring H-Plane ripple of ±0.1 dB, it ensures high symmetry and measurement reliability. Designed with a maximum VSWR of 2.1:1 and a precision 50-ohm SMA-Female connector interface, it serves as an indispensable reference standard for OTA anechoic chamber testing, wireless mobile terminal evaluations, and laboratory RF calibration.
