Physical cable characteristics are:
diameter = 7.5 mm,
maximum installed cable length = 65 meters or 35 meters cable 5916 or
45 meters or 22 meters cable FILOTEX,
minimal bend radius = 40 mm,
minimal bend radius = 100 mm for a "drip loop".
Steps
1. Install the 75 ohm connector between the X-Pol RT unit and the NT unit.
Note: In the event of the use of splitters, use the number of cables required by the configuration.
Note: Make a drip loop where the cable enters the building, respecting the cable's bending radius
(100 mm minimum), in order to prevent water infiltration.
2. Record the length of the cable installed in the 7390 X-Pol RT cabling sheet. This information will be
entered into the database when the equipment is commissioned using the configuration software.
Note: The accuracy required by the configuration software is ± 1.5 m.
3. At the X-Pol RT, install a type "F" 75 ohm coaxial connector (designed for outdoor use) on the cable.
Refer to the manufacturer’s Assembly manual and use the specific tools as recommended for
installing the connector. One of the main causes of installation problems is the faulty installation of
connectors.
AVOID LONG CABLE RUNS PARALLEL TO CABLES THAT COULD CAUSE
INTERFERENCE (E.G. AC POWER OR GSM/DCS BASE STATION CABLES)
ALWAYS USE A "F" CONNECTOR WITH A CENTER PIN NOT EXCEEDING 0.042 INCH.
DIAMETER ANY OTHER CONNECTOR IS USED, THE X-Pol RT COULD BE DAMAGED
IMPORTANT NOTE: NEVER HANDLE THE X-Pol RT UNIT BY ITS ANTENNA. ALWAYS
HANDLE THE UNIT BY THE BODY OF THE RADIO OR THE SUPPORT ARM
IMPERATIVE : PROTECT THE "F" CONNECTOR CONNECTION WITH
A PRE-PASTED THERMOSHRINKABLE SLEEVE
