Extened Range (ER) Equipment
The ER Equipment allows for the use of different external antennas to achieve links of much longer
range (up to 66 kms). It can also be used for indoor installation of the units should severe weather
conditions require it. The antenna is then mounted outdoors and connected via appropriate RF
cables to the unit.
The Libra 5800 ER consists of three parts: 1) ER, 2) Ethernet Power Inserter with CAT-5 cable
(bought separately) and weatherproofing kit (included), and 3) the External Antenna and cable (both
bought separately).
• LIBRA 5800 ER – The ER is the main piece of equipment. It is designed for outdoor
installation but can also be installed indoors if needed. The ER is equipped with an N-type
connector so that the external antenna can be connected to it. Thus the range of the P-P
system can be significantly increased by use of higher gain antennas. Also, in situations
where very severe conditions may be encountered outdoors the ER can be installed indoors
with cabling to the antenna outside.
• Ethernet Power Inserter – This piece of equipment is a small box that connects between the
ER and the Ethernet network. This box also provides power for the ER equipment to run. A
CAT-5 outdoor cable is used to connect the Power inserter to the ER. The weatherproofing kit
is used with standard RJ-45 connector to ensure reliable connection for outdoor systems.
• Antenna and Cable – In order to accomodate different range requirements for P-P links, the
ER is designed to be used with an external antenna. Antennas and cables are selected by
the user based on the network requirements.
