丨 Product Introduction
AK701 multi-system multi-band antenna delivers precise positioning with centimeter-level accuracy for error-free operations; robust anti-interference and lightweight design make it ideal for UAVs in complex working environments.Features：
1. Multi-Arm Helix Tech
Multi-arm helix design enables efficient right-hand circular polarization, optimizing signal reception & phase center stability. Reduces measurement errors, boosting positioning accuracy/reliability.
2. High Gain & Low Roll-Off
High-gain with minimal roll-off: maintains strong reception even for low-elevation satellite signals, enhancing overall signal stability/coverage.
3. Low-Noise High-Gain Amplifier
Precision amplifier + excellent out-of-band suppression cuts background noise & boosts signal strength. Performs well for weak signals in high-interference environments.
4. Compact & Lightweight
Small, lightweight build: easy to carry/install, ideal for mobile/rapid-deployment applications.
