1.3 Rooftop RET Configurations

Rooftop conﬁ gurations with RET equipment are possible. For example, each wall could have an

antenna with an actuator. A RET cable can be run from each actuator to a junction box; and then

a longer RET cable can be run from the junction box to the controller. Accessories (e.g. grounding

kits, lightning protection units, etc.) can be added, as needed. See Figure 1-4 for a simpliﬁ ed dia-

gram example.
