Product Description

The SMG540 provides four cellular feeds for 4×4 MIMO equipment plus active GNSS in one 4-inch surface-mount radome. Its cellular paths cover 617 MHz through 7.2 GHz for broad Sub-6 network support.

Integrated positioning: Choose standard GNSS, GPS-only or optional tri-band L1/L2/L5 positioning without adding a second antenna housing.

Protected enclosure: The low-profile ASA radome is IP67 rated, impact rated IK07 and ground-plane independent.

Example Model Configurations: SM540-7C00-B-12, SMG540-7C2C-B-12, SMT540-7C2C-B-12
