Connecting Server Antenna(s)
The CU has an N-type(f) connector on the top of the unit for attaching an antenna. An Omni-
directional antenna may be used (for example in open spaces), or a coaxial cable can be
connected with a series of passive antennas attached (best for hallways and office spaces).

d. Cabling the NU or HUB to the CUs
Each CU connects to the NU or HUB using two category cables. QUATRA signaling is not
Ethernet compatible, so routers, switches, bridges or other active Ethernet devices may not
be used. Patch panels or punch-down blocks may be used.
