Revision 12-03
Below is a list of the most common remote units that are used with the DeltaNode Fiber-DAS system.
Variants are available upon request.
Commonly for all Remote Units is their excellent noise figure, contributing to an overall noise figure for
the whole system from remote to head-end into the base station of < 3 dB for the RF link.
Both chassis comply with IP65 protection for use in any environment. The coating is a durable coating
which aids the convection cooling. No fans are used for the Remote Units. Both chassis are available both
with wall and pole mounting kits as requested.
