The Gemini LTE 4G MIMO 2X2 is a robust external antenna that is fully IP67 waterproof for use with all 2G/3G/4G MIMO cellular routers and Access points worldwide. It includes two embedded high efficiency LTE MIMO antennas. The antenna elements operate at all common and 4G LTE bands worldwide; 698-960MHz, 1710-2170MHz, 2490-2690MHz, which also include the 2G and 3G bands, meaning the antenna can also be used as fallback on 2G or 3G applications. High isolation and low ECC between the two embedded MIMO antennas prevents self-interference. Low loss cables are used to keep efficiency high over long cable lengths up to 5 metres.
