The Oscar 421 is a high-performance directional 4G panel antenna, designed to cover key frequency bands from 700 MHz to 960 MHz and 1.6 GHz to 2.7 GHz. With two ports for MIMO configurations, this antenna is ideal for improving signal strength and data throughput in 4G LTE networks. Its directional design allows for higher gain by focusing the signal towards the front, making it perfect for environments such as stadiums, shopping malls, and other large, open areas that require strong, targeted coverage.
The Oscar 421’s UV and water-resistant radome ensures reliable operation in harsh outdoor conditions. It comes equipped with a stainless steel bracket and U-bolt clamp for easy mast mounting.
The Spectral View Diagram visually describes the performance of the antenna from 400 MHz to 6000 MHz. Key frequencies are marked highlighting the technology used and the colour represents the performance at that frequency taking in to consideration the VSWR and radiated efficiency of the antenna.
Green is considered a suitable band, amber is adequate in good signal conditions and red is likely to be unsuitable.
