[Figure III-8] ACR Link Cable Connection Drawing 1) RF & GPS Cable Installation Basic procedure for Cable Installation is as follows. 1) General Items for Cable Installation l Path Examination Examine cable installation path by following steps.

Find out cable installation path from Pylon Antenna to RAS System.

- 40 -

Select the path that can minimize the length of cable.

Select the path that causes no damage or obstructions for cable installation. l Cable Selection Signal attenuates as it travels through cable. Depends on the cable type and manufacturer, cable attenuation differs. Accordingly, attenuation rate must be considered at the time of cable selection. Below table shows the attenuation rate on most widely used GPS cables. The value represents the attenuation rate of signal strength per meter. Cable Type RC8 RG58 RG213 RG214 LMR400 Attenuation Rate 0.31 dB/m 0.63 dB/m 0.35 dB/m 0.328 dB/m 0.203 dB/m l Cutting Cable cutting encompasses calculation of exact cable length required and cutting of cable using a hacksaw or appropriate tools. When cutting cable, pay attention to following details.

Cut the cable to the exact length calculated.

Mark the cutting points and cut the cable neatly so the sections would form perfectly square angles.

Tilt the cable at the time of cutting in order to prevent penetration of moisture, iron, lead, debris, dust, or other foreign substances.

Use hacksaw or file to cut the cable.

Using solvent, wipe the cutting plane clean.

Using a brush, wipe off the corners of cable. l Cable Installation Following is the instruction for Antenna Cable Installation.

- 41 -

Connect cable from the Antenna on Pylon to Arrestor.

Connect Arrestor to Main Grounding Box (MGB). Then take the cable from arrestor and connect with cable joint of RAS. In case Antenna Cable needs to be brought in to station, use common duct in the station. If common duct doesnt exist, bring it in through window.

Special cautions to be taken for cable installation are as follows.

Place a mat before working with cables to protect cable surface. If damage is found outside the cable, cut out the damaged part before installation.

After connecting antenna and cable, finish with heat shrink tube to protect joints.

Attach indication tapes on both ends of cable for ease of identification.

When fixing cables with clamp, keep the distance between the clamps to 1.5m.

When connecting cables to Rack, Antenna, or Arrestor in machinery room, firmly tighten the cables to prevent outbreak of reflected waves.

Use jumper cables for connections between Rack and Arrestor, and between Antenna and 7/8 cable. Make sure that jumper cables are not entangled.

Radius of curvature should be as big as possible, and wiring has to be performed with at least a minimum radius of curvature.

Make sure that cables are not disturbed by passage of people or equipment such as pylon ladder.

Link connector to antenna in a straight line. After linkage is made, be careful not to put excessive pressure.

Use Vinyl tape for use of electrical equipment (Vinyl tape hereafter) and heat shrink tube on Connectors external exposure in order to prevent water leakage.

Wrap around with vinyl tape more than twice and with self adhesive rubber tape more than 3 times on connectors joints and then cover with heat shrink tube.

When connecting with 1.2 and 7/8 cables, widen the joining part of 1/2 cable to 7/8 using vinyl tape and cover with heat shrink tube. 2) RF Cable Deployment
