## Long description

QuMax Omni is an integrated omni-directional MIMO 4x4 antenna designed for use with the Teltonika TRB500 gateway. The unit provides multi-band LTE and 5G coverage from 617 MHz up to 3.8 GHz and includes an internal compartment to install the TRB500 router within an IP67-rated outdoor housing. The kit includes a PoE splitter that separates data and power over a single Ethernet cable while preserving gigabit speeds and protecting the LAN port from overvoltage, short circuit, or improper connection. Note: this antenna does not support Band 32 or n77 frequencies above 3800 MHz.
Advantages
The QuMax Omni combines a 4 dBi omni-directional antenna array with a weatherproof enclosure and an internal mount for the Teltonika TRB500, enabling a compact all-in-one outdoor solution. It supports wide frequency ranges for LTE and 5G connectivity, provides vertical polarization for consistent MIMO performance, and includes a PoE splitter to simplify installation and protect the gateway. The IP67 housing enables use in exposed outdoor environments and moving applications.
Suitable for
Trains and other rail vehicles
Buses and coaches
Yachts and marine vessels
Campers and RVs
Rural or remote locations needing improved cellular signal

How to use
Mount the QuMax Omni antenna in a suitable outdoor location with clear exposure to the sky and cellular signals. Install the Teltonika TRB500 into the internal compartment according to the manufacturer's instructions and connect the included PoE splitter to a compatible PoE injector or switch. Run a single Ethernet cable to supply both data and power; the PoE splitter will separate power and data to the router while maintaining gigabit throughput. Verify connections and secure all cable entries to preserve IP67 protection.
Usage recommendations
Place the antenna on a stable, vibration-minimised mounting point and avoid mounting inside enclosed metal structures. For moving vehicles, ensure all cable glands are tightened and routed to prevent chafing. Check supported frequency bands of your operator: Band 32 and n77 above 3800 MHz are not supported by this antenna.
