Antennas and RRU installation

- Stainless steel bolts, doublenuts

- Double nuts needed forAntenna fixation

- Use the old antennagrounding cable for the newantenna after swap

- Stainless steel bolts, Spring

washer and nut.

If there is available space on

the Tower , the 2 RRU shouldbe of different types ( 3G & 4G) for each sector .. 4G on theleft and 3G on the right

If there is no availab

install 2 RRU for eacwe can install 3 RRUbut they should be type 3G or 4G

Antenna Mechanical Tilt

This small triangle using todefine mechanical down tilt

The HW Tri-band antenna length is 2.6 meters, should set mechanical tilt according to the ma

Record and call OMC to confirm the M-tilt value of all the sectors
