Certain technologies will require the installation of a GPS antenna for synchronization. As part of the deployment a GPS antenna needs to be installed externally. Optus is responsible to supply and install the GPS antenna as part of the BTS installation works for non-dual integration sites. For Dual Integration Vodafone led sites, Optus will supply GPS antenna (and ancillaries) as a part of BOM and VHA will perform the installation. Note, space needs to be allowed in the gland window for the GPS antenna cable.
