2.1.2 SmaRT BU-9H16AF-8F-8V-RS-EXT
Additional space must be considered for the base unit external antenna when mounting the BU-
9H16AF-8F-8V-RS-EXT. Make sure the unit is mounted so that there is a clear, unobstructed
line of sight to minimize communications problems. See Figure 4 for mounting dimensions. For
optional antenna extensions, please refer to Heading 4.0, Available Options. Installation of an
extension antenna kit—J5-07 3ft. extension in our example—is shown in Figure 5.
 Note: The SmaRT BU-9H15AF-EXT external antenna is hinged with 0° and 90° detents so
that the antenna can be set at an 0° or 90° angle. Angles between 0° or 90° can be
achieved, but they are not firmly set and may be prone to move during equipment use.
