Hi-Target · AH-3232
AH-3232 Dual-band GNSS Antenna.
18 grams. 27.8 mm diameter. Multi-constellation dual-band GNSS tracking in the smallest antenna Hi-Target makes — designed for drones, robots, USVs, and any platform where every gram and every millimeter counts.
The AH-3232 solves the integration problem that stops hardware teams from adding precision GNSS to small platforms. At 18 grams and Φ27.8 mm × 54.7 mm, it fits where geodetic antennas can't — on compact UAVs, micro-USVs, warehouse robots, precision agriculture controllers, and autonomous navigation systems. The LNA features excellent out-of-band rejection that suppresses electromagnetic interference from motors, radios, and power systems sharing the same chassis.

Designed for Integration
Precision GNSS in the smallest package possible.
Most GNSS antennas are designed for survey poles. The AH-3232 is designed for circuit boards, airframes, and robot chassis. Its SMA connector bolts directly to any standard RF interface. At 18 grams, it adds negligible payload to even the smallest UAV platforms. And IP67 sealing means it operates reliably in rain, dust, and spray without protective housing.
The LNA's excellent out-of-band rejection performance is the specification that matters most for integration engineers. Motors, ESCs, Wi-Fi radios, and video transmitters all generate electromagnetic interference — the AH-3232's front-end filtering suppresses those signals before they reach the GNSS receiver, ensuring stable and reliable positioning even on electrically noisy platforms.

Key Features
Six reasons integration engineers choose the AH-3232.
FEATURE 01
Multi-constellation dual-band — GPS, GLONASS, BDS, Galileo, QZSS, NavIC, SBAS.
Dual-band coverage (1197–1278 MHz lower, 1559–1609 MHz upper) tracks GPS L1/L2, GLONASS G1/G2, BDS B1/B2/B3, Galileo E1/E5b/E6, QZSS L1/L2, NavIC, and SBAS. Six constellations in 18 grams. This isn't a single-frequency patch antenna — it's a full dual-band receiver front-end with the signal quality required for centimeter-level RTK and PPK on downstream GNSS boards.
FEATURE 02
Out-of-Band Rejection
LNA suppresses electromagnetic interference from motors, ESCs, radios, and power systems. Critical for drones and robots where the antenna shares chassis with noisy electronics.
FEATURE 03
18g · Φ27.8 × 54.7mm
Lighter than two AAA batteries. Diameter smaller than a coin. Fits directly onto PCBs, airframes, and robot chassis via standard SMA thread.
FEATURE 04
35dB LNA · ≤1.5dB Noise
High gain, low noise. VSWR ≤2. Operates from 3–16 VDC at ≤35 mA — compatible with 3.3V or 5V logic-level power supplies directly.
FEATURE 05
IP67 Sealed
No radome, no housing, no protective cover needed. The antenna itself is IP67 rated — operates in rain, spray, and dust storms without degradation.
FEATURE 06
SMA connector. Plug-and-play integration.
Standard SMA male thread connects directly to any SMA-female equipped GNSS receiver board — u-blox, Septentrio, NovAtel, Hi-Target, or any other OEM platform. No adapters, no pigtails, no custom cables for most integrations. For bulk OEM orders, Hi-Target supports customization of connector type, cable length, and mounting interface.

Frequently Asked
Common questions about the AH-3232.
What is the AH-3232 GNSS Antenna?
+
An 18-gram ultra-compact dual-band GNSS antenna (Φ27.8mm × 54.7mm) tracking GPS, GLONASS, BDS, Galileo, QZSS, NavIC, and SBAS. Designed for UAVs, USVs, robots, and any platform where size and weight are the primary constraints. IP67, SMA connector, 3-16VDC at ≤35mA.
What platforms is the AH-3232 designed for?
+
UAVs/drones (PPK/RTK), unmanned surface vessels, autonomous guided vehicles, warehouse robots, precision agriculture equipment, structural monitoring nodes, and any OEM hardware requiring multi-constellation GNSS in a minimal form factor. SMA connector and 18g weight make integration straightforward on virtually any platform.
How does the AH-3232 compare to the AH-4236?
+
AH-3232 (18g, Φ27.8mm, ≥2dBi) is the smallest — dual-band, no L5/L-Band. AH-4236 (50g, Φ48mm, ≥4dBi) is slightly larger with full tri-band including L5 and L-Band. Choose AH-3232 when every gram matters. Choose AH-4236 when you need L-Band PPP or higher gain.
Does the AH-3232 support RTK positioning?
+
The AH-3232 is a passive antenna — it receives and amplifies GNSS signals. RTK capability depends on the GNSS receiver board it connects to. Paired with a dual-frequency RTK receiver (u-blox F9P, Septentrio mosaic-X5, etc.), the AH-3232 provides the signal quality needed for centimeter-level RTK and PPK positioning.
Does Hi-Target offer custom connectors for OEM orders?
+
Yes. For volume OEM orders, Hi-Target supports customization of connector type, cable length, and mounting interface. Contact Sicher 3D for OEM pricing and MOQ details.
