Overview

The TOXU TX-A90 is a dual-cable outdoor directional panel antenna developed for compatible 4G LTE routers, cellular gateways, wireless modems, CPE, signal-distribution equipment, remote-monitoring terminals, and industrial communication systems operating within 698–2700MHz.

Unlike an omnidirectional antenna that distributes energy around the installation point, the TX-A90 uses a directional panel structure. It should be aimed toward the intended cellular base station, gateway location, or target coverage area to obtain suitable system performance.

The antenna is equipped with two RF cable outputs for compatible 2×2 MIMO cellular equipment. When connected to two antenna ports on a compatible router or modem, the dual-polarized configuration can support the equipment’s MIMO communication architecture.

The listed configuration provides 18dBi nominal gain, 50Ω impedance, VSWR of no more than 1.8, vertical and horizontal polarization, and maximum input power of 50W. The antenna housing measures approximately 210 × 210 × 25mm and weighs approximately 0.6kg.

The available legacy product information contains a gain conflict: the product title lists 18dBi while the old parameter table lists 22dBi. This page therefore uses the more conservative 18dBi value. Final gain, frequency response, cable configuration, connector type, and radiation performance must be confirmed through an approved specification and sample testing before volume production.

Key Features

698–2700MHz Wideband Cellular Coverage

The TX-A90 covers common cellular frequencies between 698MHz and 2700MHz for compatible 4G LTE routers, modems, gateways, CPE, and industrial communication equipment.

2×2 MIMO Dual-Cable Configuration

Two RF cable outputs support connection to compatible cellular equipment with two external antenna ports. Both antenna ports should be connected according to the equipment manufacturer’s MIMO configuration requirements.

Directional Panel Radiation

The directional structure concentrates coverage toward the front of the antenna. Correct antenna direction and alignment are important for achieving suitable signal reception and transmission performance.

18dBi Nominal Gain

The listed configuration uses a conservative nominal gain value of 18dBi. Actual installed performance depends on frequency, antenna direction, cable loss, connector loss, mounting height, base-station location, surrounding structures, and the complete RF system.

Dual Polarization

The antenna supports vertical and horizontal polarization through its dual-port structure for compatible MIMO cellular communication systems.

Low-VSWR RF Configuration

The listed VSWR is no more than 1.8 under the approved test configuration, helping provide suitable impedance matching within the specified operating bands.

Outdoor Fixed Installation

The panel housing and metal mounting hardware support installation on a suitable pole, mast, or fixed structure. The exact bracket configuration and included accessories must be confirmed before ordering.

Compact Panel Housing

The antenna housing measures approximately 210 × 210 × 25mm, providing a compact directional antenna structure for fixed cellular communication installations.

Custom Cable and Connector Options

Cable type, cable length, and RF connector configuration can be evaluated according to the customer’s router, modem, gateway, enclosure, and installation distance.

OEM and ODM Support

TOXU supports antenna matching, RF cable processing, connector integration, mounting-bracket evaluation, sample verification, customized labeling, branding, packaging, and volume production.

Technical Specifications

The listed values are based on the currently available TX-A90 product information. The legacy title and parameter table contain different gain values. Final frequency coverage, gain, VSWR, cable, connector, polarization, mounting accessories, and environmental performance must be confirmed in the approved product specification before production.

Applications

• 4G LTE Routers

• Industrial Cellular Gateways

• Wireless Modems

• Cellular CPE

• Fixed Wireless Access Equipment

• Remote-Monitoring Systems

• Industrial IoT Gateways

• Cellular Security and Surveillance Equipment

Application suitability depends on the exact cellular bands, router or modem configuration, antenna-port quantity, RF connector, cable loss, network coverage, base-station direction, mounting height, surrounding obstacles, and local regulatory requirements.

System Integration

Before ordering, customers should confirm the exact cellular bands supported by their router, modem, gateway, or CPE. The general descriptions “4G” or “LTE” are not sufficient for final antenna selection because equipment designed for different countries and operators may use different cellular bands.

The TX-A90 uses two RF cable outputs for compatible 2×2 MIMO equipment. Both cables should normally be connected to the corresponding external antenna ports on the router or modem. Customers should confirm that their equipment supports two external cellular antenna connections.

The exact RF connector cannot be selected from product appearance alone. Standard SMA, RP-SMA, N type, and other connectors have different mechanical and center-contact structures. The equipment-side connector and required antenna-side connector must be confirmed before production.

As a directional panel antenna, the TX-A90 must be aimed toward the intended cellular base station or service area. Installation direction should be adjusted while checking actual signal indicators such as RSRP, RSRQ, SINR, RSSI, data rate, and connection stability when supported by the connected equipment.

The antenna should be installed as high and clear of surrounding obstructions as practical. Walls, roofs, trees, buildings, metal structures, and terrain can weaken or reflect cellular signals and affect the most suitable antenna direction.

The dual-polarized panel should be installed according to the approved mounting orientation. Incorrect rotation or alignment may reduce the benefit of the vertical and horizontal polarization configuration.

Cable attenuation increases with cable length and operating frequency. Long cable runs can offset part of the antenna gain, so a suitable low-loss 50Ω coaxial cable should be selected according to the installation distance and highest operating frequency.

If installed outdoors, the mounting bracket should be securely fixed, and the installer should evaluate wind loading, connector sealing, cable-entry protection, drainage, grounding, lightning protection, and strain relief. The currently available information does not provide a verified IP rating or wind-load rating.

The antenna itself is not a cellular signal amplifier and does not generate additional RF power. Actual communication improvement depends on base-station coverage, antenna direction, modem performance, cable loss, installation height, obstacles, interference, and the complete communication system.
