The Guardian MA963 is a 4-in-1 combination panel antenna for 5G and LTE routers and IoT gateways. Its four wideband MIMO elements cover 617 to 5925 MHz. That range spans worldwide LTE bands, 5G NR Sub-6 GHz bands n77, n78 and n79, the 600 MHz Band 71, and CAT-M1 and NB-IoT, with 3G and 2G fallback. A single installation can serve a wide range of modems and carriers. Full 4x4 MIMO needs efficient, well-isolated antenna elements. Taoglas designed the Guardian for high isolation between its four elements to prevent self-interference. Each element has its own 3 m low-loss TGC-200 coaxial cable ending in a straight SMA(M) connector. All performance figures are measured with the 3 m cables attached. Peak gain reaches 4.76 dBi in the 2490-2690 MHz range and up to 4.71 dBi across 1710-1990 MHz. Every listed band marked as covered exceeds 20% efficiency. The housing is ASA and measures 146 x 134 x 20 mm. It weighs 730 g and is sealed to IP67. It fixes in place with 3M adhesive, so the panel can go on a vehicle roof, a dashboard or an interior surface without drilling. It operates from -40°C to 85°C and handles up to 2 W input power. The antenna is RoHS and REACH compliant. Typical uses include IoT gateways and routers, HD video streaming, and transportation and telematics deployments where a single low-profile antenna needs to feed a four-port cellular router.
