Figure 3-11 Lightning protection of RF antenna & feeder
II. Lighting protection for dual-satellite synchronization antenna & feeder
GPS/GLONASS dual-satellite synchronization antenna & feeder should be under the
protection of the lightning arrester as shown in Figure 3-11.
Other lightning protection measures include:
Grounding of feeder at three points: In actual implementation, the number of
l
grounding points depends on the length of the feeder.
External lightning protector: In normal condition, a lightning arrester is connected
l
at antenna side and BTS equipment side respectively, so as to avoid the
possible damage to the BTS equipment and antenna caused by the lightning
current induced by feeder core.
Build-in lightning protection unit. The lightning protection unit on MBPB can
l
restrict the residual voltage from the lightning protector, so as to protect the
satellite receiver card.
