GSM Antennas
GSM Antennas can increase the mobile phone signal strength to your GSM Alarm and are a direct replacement for any existing aerial. Additional cable can be purchased so they can be mounted outdoors if required.

This high gain +3.5db antenna can be used to boost the mobile phone signal strength on the Elite House Alarm or Medilarm Classic. It simply screws in to where the previous aerial attached and has a magnetic base.
