Atlona Omega 4K/UHD HDMI/USB over HDBaseT Transmitter (330') - AT-OME-EX-TX

Product Overview

The Atlona AT-OME-EX-TX is an HDBaseT transmitter designed for 4K/UHD HDMI and USB extension over category cable in commercial meeting rooms, conference rooms, and video conferencing spaces. Part of the Omega Series, it transmits video up to 4K/60 Hz with 4:2:0 chroma subsampling, plus audio, control, Ethernet, and USB 2.0 over distances up to 330 feet (100 meters) using CAT6/6a/7 cable. The integrated USB hub supports a host PC connection and two peripheral ports, making it a purpose-built HDBaseT transmitter for HDMI and USB video conferencing deployments and collaborative meeting spaces. Paired with a compatible Omega Series receiver or switcher, the AT-OME-EX-TX delivers a cost-effective 4K HDBaseT extension solution for presentation and soft-codec conferencing applications.

Product Description

The Atlona AT-OME-EX-TX is a low-profile HDBaseT transmitter that extends 4K/UHD HDMI video, multi-channel audio, USB 2.0, Ethernet, RS-232, and IR over a single CAT6/6a/7 cable run up to 330 feet (100 meters). It accepts a single HDMI 2.0 input supporting resolutions up to 4096x2160 at 60 Hz (4:2:0) or 30 Hz (4:4:4), with full HDCP 2.2 compliance for protected content delivery. The on-board USB hub provides one USB Type-B host port for a connected PC and two USB Type-A peripheral ports for devices such as speakerphones, microphones, cameras, or keyboards, enabling complete USB peripheral integration without a separate USB extender. The unit is HDCP 2.2 compliant and passes through CEC, RS-232, and IR control signals from the receiver end back to connected sources and displays. Remote powering via IEEE 802.3af PoE from a compatible Omega Series receiver or switcher eliminates the need for local AC power at the transmitter, simplifying installation under conference tables or in furniture. The low-profile 1.02-inch chassis fits cleanly in confined installation environments. An integrated 10/100 Mbps Ethernet port provides IP pass-through to the receiver for network-connected AV systems. Front panel LED indicators confirm power and HDBaseT link status at a glance. Field-updatable firmware via the mini-USB port ensures long-term serviceability. Surface mounting hardware is included for flexible deployment in tabletop, ceiling, or furniture applications. The AT-OME-EX-TX is sold individually and is also available as part of the AT-OME-EX-KIT bundle with a matching receiver.

Frequently Asked Questions

Q: What cable type is required to achieve 330 feet (100 meters) of 4K/UHD extension?

CAT6, CAT6a, or CAT7 cable is required for 4K/UHD transmission at the full 330-foot distance. CAT5e cable supports 4K/UHD up to 295 feet (90 meters). For all installations, shielded twisted pair (STP) cable is recommended for best HDBaseT performance in electrically noisy environments.

Q: Does the AT-OME-EX-TX require a local power supply?

No. The AT-OME-EX-TX is powered remotely over HDBaseT via IEEE 802.3af PoE from a compatible Atlona Omega Series receiver or switcher such as the AT-OME-EX-RX, AT-OME-SR21, or AT-OME-PS62. No local AC power adapter is needed at the transmitter location.

Q: What USB devices can be connected to the AT-OME-EX-TX?

The transmitter supports USB 2.0 peripherals and USB 3.0 devices operating in USB 2.0 compatibility mode, including speakerphones, microphones, webcams, keyboards, and mice. The maximum aggregate USB data rate over the HDBaseT link is 120 Mbps. Refer to Atlona's Omega USB Peripheral Compatibility List for tested device recommendations.

Q: Is the AT-OME-EX-TX compatible with all Atlona HDBaseT receivers?

The AT-OME-EX-TX is designed for use with Omega Series receivers and switchers with HDBaseT inputs, including the AT-OME-EX-RX, AT-OME-SR21, AT-OME-RX11, AT-OME-RX21, AT-OME-RX31, and AT-OME-PS62. It is not compatible with the Atlona HDVS-300 system for USB extension.

Q: What is the maximum 4K resolution the AT-OME-EX-TX supports?

The AT-OME-EX-TX supports 4096x2160 (DCI 4K) and 3840x2160 (UHD 4K) at up to 60 Hz with 4:2:0 chroma subsampling, or at 30 Hz with 4:4:4. HDMI data rates up to 10 Gbps are supported from PCs, media players, and Ultra HD Blu-ray sources.

Q: Can the AT-OME-EX-TX pass protected (HDCP 2.2) content?

Yes. The AT-OME-EX-TX is HDCP 2.2 compliant and will pass HDCP 2.2-protected content streams provided the connected receiver or switcher is also HDCP 2.2 compliant. HDCP 1.4 content is also supported.

Q: How is the AT-OME-EX-TX installed in a conference table or furniture?

The unit ships with surface mounting hardware and measures only 1.02 inches in height, allowing installation in shallow cavities under tables, in lecterns, or within furniture enclosures. Cable access products such as the AT-PKT-3H can provide a professional finish for tabletop HDMI and USB connections.

Q: Can the AT-OME-EX-TX be purchased as a kit with a matching receiver?

Yes. Creation Networks offers the AT-OME-EX-TX as a standalone transmitter. It is also available as part of the AT-OME-EX-KIT, which pairs the transmitter with the AT-OME-EX-RX receiver for a complete 4K HDBaseT and USB extension solution. Visit creationnetworks.net to explore bundle options.
