• Integrated OVP 5 kA (REL3 HW)Integrated OVP 5 kA (REL3 HW)• RET connector integrated to unit RET connector integrated to unit

(REL3 HW)(REL3 HW)• Needed only when RET used Needed only when RET used

and RET motor and RET motor notnot integrated to integrated to antennaantenna

• DC line current/voltage DC line current/voltage monitoring (REL3 HW/RU40)monitoring (REL3 HW/RU40)

• TX/RX level monitoring in fiber TX/RX level monitoring in fiber (REL3 HW/RU40)(REL3 HW/RU40)

RET = Remote electrical (antenna) tiltOVP = Lightning protectionAISG = Antenna device signaling protocol

WITH existing TMA PRODUCT

Use existing TMA - • If a TMA is currently present, it If a TMA is currently present, it

can be used as a control for the can be used as a control for the RET function.RET function.

• So there will be no amplification So there will be no amplification but just a control function.(This but just a control function.(This has been confirmed)has been confirmed)

• If higher protection level 15 kA If higher protection level 15 kA FSES needed FSES needed

• FSES used in system moduleFSES used in system module• Integrated RET connectorIntegrated RET connector

• Needed in case where RET Needed in case where RET used and RET motor used and RET motor notnot integrated to antennaintegrated to antenna

• If RET integrated to antenna If RET integrated to antenna AISG signal fed via feeder line AISG signal fed via feeder line -> no need for RET connector-> no need for RET connector
