Product overview
The Hi-Target AH-3232 uses a multi-arm helical antenna architecture for satellite navigation reception in portable equipment and UAV installations. Its supported signals cover BDS B1, B2 and B3; GPS L1 and L2; GLONASS G1, G2 and G3; and Galileo E1, E5a and E5b. The two operating frequency windows are 1176–1278 MHz and 1551–1612 MHz. Right-hand circular polarization, 360° horizontal coverage and a phase-center error of ≤2.0 mm define key antenna characteristics for navigation integration.
The antenna occupies a diameter of 27.8 mm and a length of 54.7 mm, weighs less than 18 g and connects through a male SMA interface. Its low-noise amplifier has a typical gain of 32 dB ±3 dB, with a supply range of 3.0–16 VDC and current consumption of ≤35 mA at 3.3 V. Operating limits include −40°C to +85°C and 95% non-condensing humidity, with IP67 protection. Customization is available to user requirements.
