Connecting the Cables to the R450 DC
The RF 450 MHz Antenna and the communications antenna connect
on the outside of the building to the R450 DC inside the building.
1. Locate an area behind the wall where the cables can thread
through to the outside of the building.
2. Secure cables to the bottom of the R450 DC as illustrated in
Figure 37.
3. Thread the cables through to the R450 DC antenna and mast.
4. Continue to work with the cables on the outside of the building.

Mounting the Antennas and Antenna Mast
Consider the following.
CAUTION: The antenna mast and stand must be grounded
to the same grounding electrode used for the building's
electrical system to ensure that all exposed, non-current-
carrying metal parts are the same potential. Refer to NEC
Article 810.
MISE en GARDE: Le mât et le support de l’antenne doivent
être mis à la terre avec la même électrode de mise à la terre
que celle utilisée pour le système électrique du bâtiment,
afin de garantir que toutes les pièces métalliques exposées
qui ne transportent pas de courant sont au même potentiel.
Consulter l’article 810 du N.E.C.
When mounting the antennas and antenna mast, it is important to
maximize the line-of-sight relationship between the RF 450 MHz
Antenna and R450 MIUs for optimum RF communications.
