Mount Remote Antenna
The length of the BNC cable can be increased by adding cables and adapters up to a maximum recommended length of 45 ft.
l
(13.7 m). The cable can be placed in any position, but the antenna must be mounted vertically and away from metal objects.
Unless it is very close to the Transmitter, the powered clock will not set to the correct time without the remote antenna
connected.
If the remote antenna is to be mounted several centimeters above the clock and if the antenna cable is to be concealed behind
l
the wall, use a single gang electrical box to be mounted horizontally behind the clock. For a straight vertical cable run, a
minimum of 0.5 inch (1.27 cm) electrical conduit should be used, coupled with the top side of the electrical box.
If a 16.5 ft. (5 m) cable extension is used and the intent is to keep as much cable concealed as possible, connect the extension
l
to the standard antenna cable prior to running the cable into the conduit.
For a concealed cable run, a 0.5 inch (1.27 cm) hole in the wall will need to be made close to where the remote antenna
l
bracket will be mounted. The antenna cable BNC plug has a straight vertical mate with the remote antenna bracket.
