1. Introduction

The DMM antenna is a 2x2 MIMO (multiple input multiple output) / diversity capable accessory antenna
designed to improve reception for 2G / 3G/ 4G and some 5G modem devices.
2.1. Desk mounting
The DMM can be screen clip mounted using the two supplied clips. Simply take the clips and slide them
upwards into the keyhole notches on either side of the base of the antenna using a firm steady action as
shown in fig. 2. When the screen mount clips are installed the desk mount feet cannot be used so the
screen clips should be removed and stored safely if the user wishes to subsequently desk mount the
antenna.
2.2. Screen clip mounting
The DMM can be suction mounted to a window or other smooth surface utilising the supplied suction cup.
Simply insert the scution cup into the central keyhole slot as shown in fig.3. Proceed to mount the
antenna by pressing it firmly onto the desired surface until a firm grip is acheived. To dismount the
antenna hold the suction cup firmly and slide the antenna upwards dismounting the antenna from the
suction cup. The suction cup can then be removed from the mounting surface with ease.
Please note that not all surfaces are suitable for suction mounting and that this method is for temporary
mounting only. The antenna should not be suction mounted to metal surfaces.
2.3. Suction cup mounting
The DMM can be easily desk mounted using the integrated fold out feet as shown at fig. 1. Simply fold
out both feet and position the antenna as desired. The feet can then be re-stowed for transport.
2. Positioning the Antenna
The DMM is designed to operate with MIMO enabled modems which are able to take advantage of the
scattered signal paths which exist in everyday indoor environments. For this reason the user can be very
flexible about where they position the antenna. The antenna is omni-directional and does not need to be
facing any particular direction to operate. The antenna should not be positioned too close to metal
objects as this may affect performance.
