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. 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.
2.A. Desk 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.B. Screen clip 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.C. 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.
3. Routing the cables
Route the dual coaxial cables from the antenna to the modem. The cables should not remain bunched or tightly
wound as this may affect performance.
4. Connecting the antenna
The antenna can now be connected to the modem using the integrated connectors or by utilising any supplied
adapter leads.
