The primary antenna for the SEM300 System Enhancement Module, supporting LTE worldwide and CAT-M bands in a 140 by 26 mm body. Order it as a replacement when the original is missing from the box or damaged during the install.
Built for the alarm installer
The primary antenna both transmits and receives, so it is the one that carries the alarm signal out. If only one antenna is fitted, this is the one the module needs.
CAT-M support matters on a module like this. It is the low-power, long-range LTE category that alarm communicators use, and it generally reaches further into a building than standard LTE, which is what keeps a panel in a basement utility room reporting reliably.
At 140 mm it routes out of a panel can without fighting the cover.
Key features
- Direct replacement for a SEM300 antenna lost or damaged during install
- LTE worldwide and CAT-M support matching the module's radio
- 140 x 26 mm so it routes out of a panel enclosure cleanly
System requirements
