iRM4451nn00-2 iRRH Product Description and Installation Guide 3-5
3.2.1 GPS connector
There is a 50-Ω GPS SMA female connector located on the bottom of the
iRM4451nn00-2 iRRH as shown in
Figure 3-4.
A GPS mounting kit is provided which allows mounting the GPS antenna on the
macro iRRH or, if required, in a remote location if it is necessary to obtain an
unobstructed view of the sky. The kit will include a bracket with mounting
fasteners, and a GPS antenna with integrated cable terminated with an N-male
connector in a length specified in the Site Plan.
For installations where multiple equipment share a remote antenna, the Installer
must supply any splitter/combiner/amplifier and other additional GPS cables,
connectors or hardware as required in the Site Plan.
The GPS cable bend radius is .0.75 in (19 mm).
3.2.2 RF connectors
There are four 50-Ù, 4.3-10 female RF jacks that terminate on the bottom of the
iRM4451nn00-2 (see
Figure 3-2). They are marked, from left to right, ANT4
