Accessories
Figure 4 ‐ 5: RADWIN GSU
The RADWIN GSU may be operated over Ethernet or connected to an HSS Unit using a
standard HSS cable. It synchronizes the transmission timing of multiple Hub ‐ Sites to a GPS
clock source thus eliminating self ‐ interference (see GPS Hub Site Synchronization )
Lightning Protector Unit (LPU)
The RADWIN Lightning Protection Unit is used for CAT ‐ 5e cables, and can work with any
RADWIN product. The use of lightning protection is dependent on regulatory and end user
requirements. The RADWIN 2000+ Series ODU is designed with surge limiting circuits to
minimize the risk of damage due to lightning strikes.

Ethernet Cable Repeater
The RADWIN Ethernet repeater enables you to extend the PoE to ODU cable beyond the
100m limit (but no more than 200m). The repeater supports 10/100baseT.
The LPU works with CAT ‐ 5e (ethernet) cables, but not RF cables. When
installing a unit with an external antenna, we recommend using a Surge
Protector along the RF cable for lightning protection.
