Overview
Passive anti-jam shield for existing antennas
SAJ is a passive shield fitted around an existing standard or CRPA antenna. It attenuates jamming and multipath arriving from 90° and beyond, adding 20–30 dB of protection without replacing the receiver chain. SAJ has been selected by domestic and international UAV manufacturers and military users and is battle-proven in the field.
Highlights
- Upgrades standard or CRPA antennas without electronics changes
- Reduces low-elevation jamming and ground multipath
- Housing adapted to each platform’s structure

Applications
Where SAJ GNSS Shield is used
CRPA antenna arrays, passive shields and repeaters that keep positioning, navigation and timing available when GNSS signals are jammed, spoofed or degraded by multipath.
- 01UAV fleets needing a fast anti-jam upgrade
- 02Combined with BORAJ CRPAs for 95–100+ dB
- 03Land vehicles and fixed sites
