The QuMax A140M is a 6dB directional 4G antenna that simultaneously acts as a waterproof enclosure for the board version of the Teltonika TRB140, an industrial IoT gateway. This enclosure's robust IP67-rated design, in conjunction with the directional nature of the antenna, guarantees that the TRB140 can be used with the most optimal performance possible regardless of environmental factors as long as a mobile mast is visible with clear line-of-sight.

The A140M is a strong directional antenna, with a dB signal strength ranging from 4-6dB and covering the primary UK frequency bands (0.694 - 960 GHz, 1.700 - 2.200 GHz, 2.200 - 2.700 GHz). Direct line-of-sight to a mast is required in order for this antenna to operate properly: this can sometimes be difficult to achieve with many other directional antennas due to the signal loss over lengthy mobile antenna cables. This antenna avoids that problem altogether by the nature of the cabling and the LTE equipment all being contained within the antenna's frame itself, meaning it can be mounted as high up and far away as it needs to be to achieve line-of-sight without having to worry about how close it is to anything else.

The A140M is constructed specifically to perfectly fit the TRB140 board inside of it. This TRB140 board will be powered via passive Power over Ethernet (PoE) which allows it to be located up to 50 metres away from the nearest power supply, offering great flexibility when it comes to finding the optimal mounting location.

* The TRB140 supports passive Power over Ethernet from revision 4 onwards (Teltonika currently provides TRB140 revision 7 or newer). If you have a pre-existing TRB140, check its revision before attempting to power it with PoE.

Article - IP Ratings Explained

IP ratings, or Ingress Protection ratings, are a standardised benchmark of how capable a product is of withstanding ingress from foreign entities that could negatively impact its functionality. They’re helpful because terms like ‘weatherproof’ and ‘waterproof’ are unspecific terms and don’t always convey the necessary level of detail – waterproof on one device can mean it’s capable of withstanding rain. In contrast, on another device, it can mean being capable of complete submersion in water for extended periods.
