Alarm.com | 18' Snap-on MMCX Antenna | ADC-9AM-18F-MMCX

Alarm.com offers MMCX antenna solutions in various cable lengths. For all antenna solutions, the cable connects the antenna to the module but just the very tip of the antenna captures the signal.

Alarm.com also offers Signal Booster Kits designed to help increase signaling in areas where there is very low signaling. It is designed by ClearRF and is normally recommended as a last resort for signaling troubleshooting. For more information, see What signal boosters are compatible with Alarm.com?. 

Note: The Qolsys IQ/DSC Touch and Qolsys IQ Panel 2 use a built-in antenna so it is not possible to disconnect the antenna on those panels. The connection between the panel and the built-in antenna is not an MMCX connection, which our extended antennas and booster kit use. 

Important considerations

• All MMCX antennas that Alarm.com offers are rated for indoor use only and cannot be used to mount outdoors. 
• All MMCX antennas should not be extended by splicing or connecting additional coaxial cables. Extending the antennas in this matter would not result in a net gain in signal strength. 
• None of the antennas are directional. They all radiate the same way in all directions that are perpendicular to the axis of the antenna tip. They should be held vertically.
