RFI CSM550-5M-SMA 5GRN Ultra Compact Antenna, 617–5925MHz, 5m LL100 Cable, SMA Male
The RFI CSM550-5M-SMA is an ultra-compact, omni-directional 5G NR antenna providing excellent coverage for M2M/IoT, fixed data, and mobile applications across 617–5925MHz. Supplied with 5m LL100 low-loss cable, terminated with an SMA Male connector.
Overview
The CSM550 series is built for space-constrained installations where a discreet, weatherproof antenna is needed. Its ultra-compact housing (just 50mm diameter, 50.8mm tall) suits both indoor and outdoor applications, and it covers all major 5G, 4G LTE, and 3G cellular bands with a single antenna.
The screw mount features an anti-rotation mechanism and an integrated double-sided foam seal, giving a secure, weatherproof fit on an 11.9mm stud mount. Being ground plane independent, it performs consistently regardless of where it's mounted, without needing a large metal surface underneath.
This version is supplied with a 5-metre LL100 cable, giving you more reach for installations where the antenna needs to sit further from the router or modem.
Key Features
- Covers 617–5925MHz means one antenna supports 5G NR, 4G LTE, and 3G across every major cellular band, for future-proof connectivity.
- Ground plane independent design means consistent performance regardless of mounting location or surface.
- Ultra-compact housing (Ø50 x 50.8mm) means a discreet fit in space-constrained installations.
- IP69 weatherproof rating means reliable performance outdoors in harsh conditions.
- Screw mount with anti-rotation mechanism means a secure fit that won't loosen from vibration.
- Supplied with 5m LL100 low-loss cable and SMA Male connector means extra reach for installations where the router or modem sits further from the antenna.
Applications
- M2M and IoT devices
- Fixed wireless data applications
- Vehicle and fleet telematics
