SUMMARY
Proposal
Basic Antenna Specification for Macro CASLoading Weight for Macro CASAdvantages & Disadvantages for all OptionsAntenna System Configuration
Option – Supply of antenna, jumper, feeder Artification
an axiata company
Proposal• There are 3 options were identified for Macro Common Antenna Systems
(Macro-CAS).- Quadband- Triband- Dualband
• RF Planning Matter (Azimuth, Tilting & RF Antenna Height)– PM has the right to determine the Azimuth, Tilting and RF Antenna
height which subject to planning requirements.– Others telcos are not allowed to adjust any azimuth and antenna tilting
without consent from PM.– Structure height should be defined by PM.
• Antenna Location– RF Antenna (mobile) on most upper level of the structure– Microwave on lower level of the structure
• RRU Location– RRU located on ground level– Sacofa to provide boom for RRU Mounting and securities for all telcos
equipments, such as caging

Advantages & Disadvantages for all Options
• All options have advantages and disadvantages• The best option from RF Planning point of view is Option 1• The best option from structure loading point of view is Option 3 but could
not accommodate all Telcos interest• The moderate option is suitable solution

Option – Supply of antenna, jumper, feeder
• Option
– Sacofa should supply the antenna, jumper and feeder for common antenna sites.
– Sacofa to provide the VSWR test acceptance. – In the event that Sacofa unable to deliver the above material
as per required date, PM have the right to provide those material and handover to Sacofa upon completion.
– Sacofa will be responsible for the maintenance, vandalism and etc related to the antenna, jumper and feeder.
– Rental substitution in contra for material supplied by PM to be further discuss for commercial concern.

Special note to sesco, we appreciate this collaboration between telcos and sesco in this workshop. As much as we face challenges in delivering with our customer needs, we believe the same could be true for sesco. We hope En. Rosli representatives from Sesco could make a difference to closing the gap on progress update on power application.
