PWR-COBRA-1 RET Antenna System Quick Installation Guide
Scope
This document briefly describes the installation and operation of the PWR-COBRA Remote
Electrical Tilt antenna system. It is intended to give an overview of basic installation and
operation for experienced antenna users.
Equipment Required
ƒ COBRA™ RET capable antennas
ƒ Antenna mounting hardware (standard or 0–15° mechanical downtilt kit included with
antenna)
ƒ Coaxial cables from BTS to antenna RF ports
ƒ CBL-COBRA one feed line and one jumper per additional antenna, or smart bias tees
and jumper cables. Bias tees eliminate the need for the one main RET cable run
ƒ PWR-COBRA-1 interface power supply
ƒ RS-232 cable (supplied with PWR-COBRA-1)
ƒ Laptop or computer with PWR-COBRA software (supplied with PWR-COBRA-1) installed
Installation Instructions
1. Install the antennas using the mounting hardware provided. Record on an Installation
Configuration sheet the antenna sector, model number, serial number, and pointing angle
from 0–360°.
2. Attach the feed lines from the BTS to the antenna RF ports.
3. Attach the female end of the CBL-COBRA homerun data cable to the first antenna
actuator input port. (The homerun cable is the data cable that runs from the base of the
tower to the input of the first antenna in the RET system.)
4. Attach the male end of the CBL-COBRA jumper line to the output port of the first antenna
and route/connect the female end to the second antenna. Repeat this process until all the
antennas are attached to the RET system in a daisy chain configuration. Cap the output
port of the last antenna with the cap cover provided. Please the see note at the end of
this document for cable length recommendations.
5. Attach the male end of CBL-COBRA feed line at the base of the tower to the barrel
connector port on the PWR-COBRA-1 interface power supply.
6. Plug the interface power supply (PWR-COBRA-1) into the power source.
7. Attach the RS-232 cable (or USB-to-Serial adapter cable) to the laptop or computer and
into the PWR-COBRA-1 interface power supply.
8. Boot up the laptop or computer and launch the COBRA™ RET application software.
9. Click on the Scan button (located under the RET/Identification tab) to search for all
antennas connected to the RET system. When the scan is complete, all the antenna
actuators will be listed by their serial numbers (Figure 1).
