## 1. Introduction 

The Colosseum MA841 antenna is a low profile, heavy-duty, fully IP67 waterproof external M2M antenna for use in worldwide telematics applications which require best in class 4G LTE MIMO performance. 

This unique product, only 30mm height, delivers powerful worldwide 4G LTE MIMO antenna technology at 700MHz/800MHz/1700MHz/1800MHz/2600MHz. 

Typical applications 

- Remote Asset and Pipeline Monitoring 

- Digital Signage 

- HD Video over LTE 

- First Responder and Emergency Services 

- Automotive Vehicle Tracking and Telematics 

4G applications demand high speed data uplink and downlink. High efficiency and high gain MIMO antennas are necessary to achieve the required signal to noise ratio and throughput required to solve these challenges. Taoglas also takes care to have high isolation between the two MIMO antennas to prevent self-interference. Low loss cables are used to keep efficiency high over long cable lengths. In contrast, smaller MIMO antennas with poorer quality thinner cables will have much reduced efficiency and isolation, which would lead to a large drop in system throughput or drops, and may indeed not make a system connection at all. 

Cable length and connector types are customizable. Contact your regional Taoglas customer support team for installation instructions or further support.
