1 MICROWAVE ANTENNA INTRODUCTION

The Hiperion Microwave Antenna is a parabolic antenna that consists of a solid reflector, ODU intake or feed and a tower mount. There are two types of antenna: The Standard Performance (SP) Parabolic Antenna and the High Performance (HP) Parabolic Antenna. The HP antenna has an additional shield and radome attached, which gives higher efficiency with reduced side lobes and a greatly improved Front to Back Ratio. The design incorporates high quality materials and anti-corrosion proofing coatings.

The free hole the shroud junction must be in front of the reflector‟s bottom hole (shroud‟s drain hole must have directed to the antenna bottom).

7.5 0.9 M ANTENNA FEED ASSEMBLY INSTALLATION

NOTE: Before feed assembly installation, put two pieces of wood strips, which are

available in the package under the reflector assembly, on the purpose of keeping

the spider away from the ground, see Figure 4.

10 ANTENNA ALIGNMENT – ALL MODELS

10.1 ANTENNA PRE-ALIGNMENT Path profile analysis will provide each installation site with the required elevation information, for initial installation it is sufficient for the antenna to be pointed in the general direction as fine tuning will take place during alignment For site installation, obtain the site installation information of each site, locate and verify the required azimuth and elevation is achieved before commencing to make any alignment to any antenna. For azimuth and elevation alignment, arrange each hop to act as Transmitter and Receiver station at any one time, alignment involves of fine tuning, and is an iterative process, to perform and establish one alignment per iteration. The objective is to maximise the receive signal at the Receiver signal for the hop. Before proceeding to antenna pre-alignment, ensure each end of the hop is equipped with known working equipment. Equip the transmitter station:

Fully equipped IDU, ODU and antenna

Set the IDU ATPC function to “disable” and that it is transmitting signal. Equip the receiver station:

ODU installed

Universal meter for RSSI measurement

10.2 ANTENNA PAIR IDENTIFICATION Assuming that correct planning, frequency coordination and site sense has been carried out for a particular installation site, it is unlikely that the receiver will receive unwanted RF signals in the frequency band generated on that site; however interference from other microwave link paths is a real possibility. With the antennas basicly set to the calculated bearings and azimuths, proceed to identify and isolate the wanted RF signal in the presence of unwanted signals. A unique „RSL lookup table‟ is supplied with each Hiperion ODU, to specify the relationship between RSL and RSSI level, however the relationship is approximately every 10 dB of RSL equals an increase of approximately 600 mV RSSI . Ensure the serial number of the ODU matches the correct „RSL lookup table‟ before proceeding.

Figure 67: RSL Vs RSSI After full antenna alignment, the antenna pair is identified when the measured RSL value matches the calculated value within +/- 2 dB. Note that “Blue Sky” conditions must exist to meet the calculated RSL.

10.3 ANTENNA FINE-ALIGNMENT Each ODU has a DC voltage connection for connection to a universal multimeter. This is a RSSI indication, and is monitored by the multimeter. RSSI indication is indicated by a voltage reading, as azimuth and elevation adjustments are made, the voltage level indicate the „closeness‟ of the optimal setting.

The above Figure 68 represents the RSSI level as the antenna is being brought into alignment. Location of the optimal signal strength should be at the maximum of its RSSI profile.

11 FINAL INSPECTION AFTER ANTENNA INSTALLATION

When the installation of the antenna has been completed, make sure that the installation instructions have been followed. It‟s especially important to check that all bolted joints are properly locked. Recommended torque values for all antennas are found in their respective sections. Make sure that the drain holes on top of antenna are blocked by plastic plugs, while that the drain holes on bottom of antenna are open. NOTE: Information in this document may be subject to changes without notice.
