UHF Intrinsically Safe Splice box with DC coupling Datasheet USDX-100 EUX
UHF Splice Box USDX-100 EUX – Intrinsically Safe
ia
Application & Description Brief
Radiating "leaky" cable systems, in which radio signals are transmitted from a cable rather than from an
aerial, can provide two-way radio services in situations where conventional VHF and UHF communications
from central areas are not practical. The radiating cable Splice Box is typically used in Mining, Shipping,
Tunneling, Motorway and In-Building radiating cable systems. This unit is used to connect two sections of
cable during installation, extensions or repairs to Leaky Feeder systems. The unit couples both the RF and
DC signals seamlessly between the two joined sections.
