Overview

The TOXU TX-G017 is an outdoor active GNSS timing antenna designed for fixed satellite-navigation reception, timing synchronization, reference-station, and infrastructure applications.

The antenna covers two frequency ranges: 1166–1218MHz and 1559–1606MHz. These ranges support reception of compatible GNSS signals operating within the specified bands. Actual constellation and signal support depends on the connected GNSS receiver.

The TX-G017 uses right-hand circular polarization and provides a specified zenith gain of 43±2dB. Its integrated active circuit has a noise figure of no more than 2dB, an output VSWR of no more than 1.8:1, and passband ripple below 2dB in both specified frequency ranges.

The active circuit operates from 3–12V DC with current consumption below 45mA. Bias power is normally supplied through the RF cable by a compatible GNSS receiver, timing module, or bias-tee circuit.

For outdoor reliability, the antenna is specified with an IP67-rated enclosure, 15kV air-discharge ESD protection, IEC 61000-4-5 surge protection, 720-hour salt-spray resistance, and an operating temperature range from -40°C to +85°C.

The standard configuration uses a nominal 50-ohm N female connector. Its white radome and pole-mounting arrangement support permanent outdoor installation on communication sites, timing stations, monitoring facilities, reference stations, and marine infrastructure.

The TX-G017 is an active GNSS antenna only. It does not calculate position, generate timing data, process RTK corrections, or replace a GNSS receiver or timing module.

Key Features

1166–1218MHz and 1559–1606MHz Coverage

The two specified frequency ranges support compatible GNSS signals used by multi-band receiving and timing equipment.

43±2dB Specified Zenith Gain

The integrated active circuit amplifies received GNSS signals before transmitting them through the connected coaxial cable.

Noise Figure ≤2dB

The specified low-noise amplifier limits additional noise introduced during GNSS signal amplification.

Output VSWR ≤1.8:1

Provides the specified RF matching performance when connected to a compatible 50-ohm system.

Passband Ripple Below 2dB

The available specification lists less than 2dB passband ripple across both 1166–1218MHz and 1559–1606MHz.

Right-Hand Circular Polarization

RHCP polarization supports reception of compatible circularly polarized GNSS satellite signals.

3–12V DC Active-Antenna Input

Supports bias power supplied through the RF connection by compatible GNSS receivers and timing equipment.

Current Consumption Below 45mA

The active circuit operates with a specified current consumption of less than 45mA.

IP67-Rated Outdoor Enclosure

The enclosure supports fixed outdoor applications exposed to dust and water when correctly installed and sealed.

15kV Air-Discharge ESD Protection

The specified electrostatic-discharge protection supports equipment installed in exposed outdoor environments.

IEC 61000-4-5 Surge Protection

The antenna includes specified surge-protection capability according to the referenced immunity standard.

720-Hour Salt-Spray Resistance

The specified salt-spray resistance supports evaluation for coastal, marine, and other corrosive outdoor environments.

-40°C to +85°C Operation

The wide operating-temperature range supports deployment in changing outdoor climate conditions.

N Female Connector

The threaded RF interface supports connection to compatible 50-ohm outdoor coaxial cable assemblies.

System Integration

The TX-G017 must be connected to a compatible GNSS receiver, timing module, reference-station receiver, or synchronization device supporting the required signals within 1166–1218MHz and 1559–1606MHz.

The antenna requires 3–12V DC bias power with current capacity above the specified operating consumption. Bias power is normally supplied through the coaxial cable by the connected receiver or a compatible bias-tee circuit.

Before connection, confirm the receiver’s antenna-bias voltage, available current, short-circuit protection, active-antenna detection, and RF input power limitations.

The standard antenna uses an N female connector. Select a compatible N male cable connector and low-loss 50-ohm coaxial cable according to the required cable length and operating frequency.

Long coaxial cables introduce insertion loss and can reduce the signal level delivered to the receiver. Cable type and length should be evaluated as part of the complete RF link budget.

For outdoor installation, mount the antenna vertically with the radome facing the sky and provide the clearest practical sky view. Avoid nearby walls, metal roofs, transmitting antennas, overhead structures, motors, and other sources of blockage, reflection, or electromagnetic interference.

The IP67 rating applies to the antenna enclosure under the specified product configuration. The mating connector, cable joint, mounting interface, grounding, lightning-protection system, and complete installation must be sealed and protected separately.

IEC 61000-4-5 surge immunity must not be treated as complete site-level lightning protection. Outdoor installations may still require professional grounding, surge arresters, lightning-protection devices, and compliance with applicable local electrical standards.

Final reception, timing, positioning, waterproofing, corrosion resistance, and surge performance should be verified on the completed installation.

FAQ

Q: What type of antenna is the TX-G017?

A: It is an outdoor active GNSS timing antenna covering 1166–1218MHz and 1559–1606MHz.

Q: Is this only a GPS L1 antenna?

A: No. It covers two broader GNSS frequency ranges. Actual signal and constellation support depends on the connected receiver.

Q: Is the 43±2dB value passive antenna gain?

A: No. It is the specified active antenna zenith gain, including the active amplification stage.

Q: What bias voltage does the antenna require?

A: The active circuit operates from 3–12V DC with current consumption below 45mA.

Q: Which connector does it use?

A: The standard configuration uses an N female connector for connection to a compatible N male 50-ohm coaxial cable assembly.

Q: Is the antenna waterproof?

A: The enclosure is specified as IP67. Final waterproof performance depends on correct sealing of the connector, cable joint, mounting interface, and complete installation.

Q: Can it be installed in coastal or marine environments?

A: The specification lists 720-hour salt-spray resistance, supporting evaluation for coastal and marine installations. Final suitability still depends on the complete mounting structure, connector sealing, materials, and maintenance conditions.

Q: Does IEC 61000-4-5 mean the antenna is fully protected from lightning?

A: No. It indicates specified surge-immunity protection. Complete outdoor lightning protection may still require grounding, external surge arresters, and professional site-level protection.

Q: Does the antenna provide timing or positioning data directly?

A: No. It receives and amplifies compatible GNSS signals. A separate GNSS receiver or timing module is required to generate position, time, or synchronization data.

Q: What are the exact product dimensions?

A: The supplied parameter table and mechanical drawing contain inconsistent dimensions. Final dimensions must be confirmed using the approved production drawing.

Q: Can TOXU provide the matching RF cable?

A: Yes. TOXU can evaluate compatible 50-ohm coaxial cable assemblies, connector configurations, cable lengths, labels, and packaging according to the installation requirements.
