2. Preliminary Decisions
AMPS EAC-2100 Manual: (Draft, 02/01) Page 2-6
2.3.4 Mounting Surface
If the wall hanging bracket is used, make sure that the wall construction and the fastening
hardware is adequate for handling at least the 210 lb (95 kg) of the EAC-2100.
If the pedestal mount is to be used, make sure that the floor or concrete surface is adequate for
handling approximately 60 pounds per square foot (300 kg per square meter). The pedestal has
mounting holes to allow it to be bolted to the floor. Bolting to a surface should be done before
the EAC-2100 is placed on the pedestal.
The EAC-2100 may be mounted either indoors or outside. If it is mounted outside, adequate
drainage away from the pad should be provided to prevent water from accumulating underneath
the cabinet.
2.4 Antennas
The EAC-2100 requires four antennas:
D1 antenna: Primary antenna facing donor cell site(s), used for:
• Reception of DCCH and DTC channel signals from donor cell site(s).
• Transmission of DCCH and DTC signals back to cell site(s).
M1 antenna: Primary antenna facing subscribers in the booster coverage area, used for:
• Transmission of boosted DCCH channel and boosted DTC channels to subscribers.
• Diversity reception from subscribers.
• Transmission of hand-back messages to subscribers.
M2 antenna: Second antenna facing subscribers in the booster coverage area, used for:
• Sending hand-in and grab-back messages to subscribers.
• Diversity reception from subscribers.
• Sending data messages to multi-hop EAC-2100s and Multi-Donor Units.
Data mobile antenna (optional): Antenna for the installed cellular mobile. Used for:
• Receiving and transmitting signals from any cell site in the system.
• In many cases the internal data mobile may be connected to the test port on the donor duplexer. This
will allow the data mobile to share the donor antenna for its link back to the donor base station.
Ensure that the proper antenna type and placement have been selected for each antenna.
