whether to install the primary protection kit at an extra cost or to rely on the secondary

Figure 11: Surge Protectors
From left to right: PolyPhaser surge protectors are used with the Combo Chassis and Split
Chassis configurations (PSX-ME for the Cal and RF cables, at the antenna, PSX for the Cal and
RF cables at the ground Buss Bar, and DGXZ+06NFNF-A for the GPS antenna cable at the
ground Buss Bar.
Huber+Suhner surge protectors are used with TTA configurations. The Female-Female model is
used for Primary Surge protection* at the ground Buss Bar (RF and Cal cables near the BTS);
and the Male-Female model is used for Primary Surge protection (RF and Cal cables) at the RFS
and with the GPS cable.
PolyPhaser surge protectors block DC, are unidirectional (there is an “equipment side” and a
“line side”), have multi-strike capability, and have no gas tubes. Huber+Suhner surge protectors
allow the DC component that powers the PAs through but stop lightning surges and electrical
transients, are bi-directional, and have a gas discharge tube.
The Navini Part Numbers for the Huber+Suhner surge protectors are 32-00228-00 and 32-00229-
00, respectively. Similar surge protectors may be obtained from NexTek (Navini Part Numbers
32-00228-20 and 32-00229-20).
