## Long description

Omni-directional QuWireless QuMax Omni for TRB500 is a compact multi-band network antenna designed to provide 360° coverage for outdoor routers and base devices. Built as an all-in-one solution, the enclosure includes a compartment for the Teltonika TRB500 gateway and an IP67-capable housing made of metal and plastic. The antenna supports multiple cellular frequency ranges from 0.617 GHz up to 3.8 GHz with a maximum gain of 4 dBi and uses vertical polarization. The package also includes a PoE splitter that separates power and data on a single Ethernet cable while preserving gigabit transfer speeds.
Advantages
The QuMax Omni delivers broad multi-band support covering key LTE and sub-6 GHz 5G ranges with stable omnidirectional radiation suitable for moving applications and rural installations. Its integrated compartment for the TRB500 gateway simplifies outdoor deployment and protects the router from environmental exposure. The included PoE splitter reduces installation complexity by allowing one-cable power and data delivery and provides basic protection for the LAN port against improper connection conditions. Compact dimensions and a durable metal/plastic enclosure make the antenna suitable for wall or pole mounting.

Use the included PoE splitter to provide power and separate data to the gateway over a single Ethernet cable, preserving gigabit throughput. Ensure all cable connections are secure and weatherproofed where necessary before powering the system.
Usage recommendations
Mount the antenna as high as practical and away from large metal obstructions for optimal omnidirectional performance. Verify supported frequency bands for your carrier and note that B32 and n77 bands above 3.8 GHz are not supported. Regularly inspect seals and cable terminations in outdoor installations to maintain reliable operation.
