Gamma Nu's GN-IYF10-16V is a slim-profiled antenna designed for operation in underground tunnels. As a wideband log design, the antenna covers major 4G bands from 700 to 2700 MHz.
This SISO antenna generates a consistent spot beam, ideal for projecting DAS coverage forward in a tunnel. The antenna provides a modest 11 to 15.5 dBi gain across the operating frequency range with a high front-to-back ratio. The low band 698 to 960 MHz is projected in horizontal polarisation, with the midband 1695 to 2700 MHz in vertical polarisation.
Designed for use by mobile network operators and DAS integrators the antenna is very low PIM, meeting -153 dBc.
Recommended Use
Gamma Nu is Korea's most prestigious antenna manufacturer, developing specialised antennas for 4G and 5G coverage augmentation.
Safety Notice
Like all high gain antenna it is important to disconnect this antenna during handling and installation. This product may generate EME that exceeds ARPANSA safety limits within 300 mm of the antenna mainlobe.
