Description & Specification
820MHz to 1GHz Precision Sleeve Dipole N-Female Antenna
CTIA Compliant Reference Standard | High Efficiency | Model: SL-82M1G-NF
The SL-82M1G-NF is a precision Sleeve Dipole Reference Antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) in Taiwan. Operating across the 820 MHz to 1000 MHz frequency band, it delivers nominal gain ranging from 0.7 to 1.5 dBi with superior radiation efficiency between 92% and 98%. Compliant with strict CTIA OTA specifications with an H-Plane ripple within ±0.1 dB, it features an overall mechanical envelope measuring 297.00 x 46.00 x 45.00 mm and weighs approximately 439.42 g. Equipped with a precision 50-ohm N-Female coaxial connector, this antenna serves as an indispensable reference standard for OTA anechoic chamber calibration, wireless device certification, and precision RF testing.
