24 / Picocell 1900 Antenna System Installation

 Method 12-0152

September 4, 1998

1.

Inspect the cable for possible damage and verify  the cable type being 
placed with the system layout. Also verify that the cable type being used 
meets the requirements for insertion loss as  specified in the layout.  See 
Table 4.  Maximum lengths and insertion Losses should be detailed on 
the System layout or floor plan.

Note: Use of a cable reel stand is recommended to minimize stress when 

placing the cable.  Maintain the cable bending radius outside the 
minimum values listed in Table 6 on page 23.

2.

Place the cable as directed in the System Layout. 

Note: When placing the RF cable equipped with connectors, use 

protective plugs to prevent connector damage. It may be 
impossible to run the cable equipped with the connector.  In this 
case run the cable to the antenna, leave slack to attach the 
connector. 

3.

Run the cable through the ceiling access hole at the antenna location and 
attach the connector to the antenna See "Picocell 1900 Antennas" on 
page 18 .

4.

Cut the cable to the desired length. 

Note: Allow enough length at each end to terminate the connector and 

allow the cable to be neatly formed to the Antenna or Hybrid. 
Coiling back excess cable is not recommended in order to 
minimize cable insertion loss.

5.

Attach  connectors and label the end of the cable according to the 
designation it has been given in the connectivity chart.

6.

Attach the connector to the appropriate output port on the Hybrid, and 
secure the cable to the mounting wall.  The cables should be neatly 
formed and secured.

Caution:  Do not apply excessive force to cable ties to avoid deforming 
or denting the cable shield. Heliax cable damaged with dents or bending 
tighter  than the minimum bending radius will degrade performance. 
Damaged cables should be replaced.
