MTUs installed inside of a building should be mounted on an exterior wall that is
not immediately facing a neighboring building. As with exterior installations, the
MTU should be mounted perpendicular to the ground with the Aclara logo facing
the installer.

Use a cellular phone’s signal strength indicator to gauge the amount of signal
interference within a building. Check the signal prior to entering the building,
and then again at the proposed mounting location. A drastic drop in cellular
signal reception may indicate potential problems with MTU transmission.
When mounting an MTU inside, it is important to note anything on the outside of
the wall that may cause interference, such as aluminum siding, or AC units.
The following illustration shows an incorrect MTU installation. The MTU is
mounted to the ceiling, facing the floor, and surrounded by copper and iron pipes.
In this case, the RF signal is not only directed towards the floor, but heavily
shadowed by the pipes.
The MTU should be mounted to the wall and away from the metal pipes, as shown
below.
