Cell Antennas (AUX and MAIN)—These SMA coaxial connectors are for attachment of cellular antennas.
The MAIN connection is for basic cellular transmission/reception, and the AUX connector is for attachment
of a receive-only antenna which provides MIMO receive operation (diversity) with standard 4G modules,
improving signal quality in many installations. In general, both antennas should always be used for cellular
operation. The GE MDS part number for this antenna type is 97-2485A04.

(GE MDS Part No. 97-2485A04)
WiFi Antenna—Antenna connection for 2.4 GHz WiFi service. The connector appears similar to the cel-
lular connectors discussed above, but is a Reverse-SMA type. It contains a pin that matches with an SMA-F
connector. The GE MDS part number for this antenna is 97-4278A48.
SIM Port—This port accepts a mini SIM card (2FF type) for 4G cell operation. The unit’s cellular interface
will not function without a valid SIM card installed. The customer is responsible for obtaining a provisioned
SIM card for the appropriate service plan from their cellular provider. Information on determining the cell
module’s IMSI/IMEI (typically required for provisioning) is provided on Page 35 of this manual.
CAUTION: Do not insert the SIM card when the unit is powered on.
Card Insertion: The SIM card only inserts one way; do not force it. It should be inserted with the printed
label facing up, and the cut-off corner on the left side (see Figure 6). This side is inserted first. A small
instrument, such as a flathead screwdriver, may be helpful to gently push the SIM all the way in until it
locks.

LED Status Indicators—The LEDs on the unit provide visual indications of the status of the device as
shown in Figure 7 and explained in Table 4 which follows.
Figure 7. LED Status Indicators
Table 4. Description of LED Status Indicators
NOTE: In addition to the LEDs above, the Ethernet connector has two embedded LEDs. A yellow indi-
cates a link at 100 Mbps operation. A flashing green indicates Ethernet data traffic.
2.4.1 Grounding Considerations
To minimize the chance of damage to the unit and its connected equipment, a safety ground (NEC
Class 2 compliant) is recommended, which bonds the chassis, antenna system(s), power supply,
and connected data equipment to a single-point ground, keeping all ground leads as short as pos-
sible.
Normally, the unit is adequately grounded if mounted with the flat brackets to a well-grounded
metal surface. If the unit is not mounted to a grounded surface, it is recommended that a safety
ground wire be attached to the screw provided on the bottom corner of the enclosure, in the
recessed flat area. Alternatively, a safety ground wire may be attached to one of the mounting
bracket screws.
The use of a lightning protector is recommended where the antenna cable enters the building; Bond
the protector to the tower ground, if possible. All grounds and cabling must comply with applicable
codes and regulations. One source for lightning protection products may be found online at
http://www.protectiongroup.com/PolyPhaser.

2.4.4 Antenna Planning & Installation
Consideration must be taken to select appropriate antennas for optimal RF performance. This section
reviews the key factors involved in selecting and installing antennas for the MCR-4G. Only approved
antennas may be used on the unit's RF output connectors, as listed in Table 5. The use of non-approved
antennas may result in a violation of FCC rules, and subject the user to FCC enforcement action.
Antenna Type and Orientation
It is important to use antennas designed to operate in the applicable cellular coverage bands with a Return
Loss of 10 dB or better. Placement of the antennas also plays a key role in the coverage of the system. While
the antennas can be placed directly on the face of the unit in some short range installations, the best perfor-
mance is obtained when mounting antennas remotely using low loss coaxial cable. Antennas mounted in
close proximity to each other can couple signals between them and desensitize the RF module.
When placing the indoor SMA style “paddle” antennas on the face of the unit, position them with a 90
degree angle of separation to improve the isolation. A “V” or an “L” configuration is a common approach
to use with the Main channel typically mounted for vertical polarization. The multipath nature of Cellular
systems means that polarization for indoor use is not normally a critical factor. Isolation between the
antennas is more important.
Note that with any installation, there needs to be a minimum 20 cm spacing between the Wi-Fi antenna and
any other radio antenna to avoid co-location difficulties.
Indoor use case:
1. This scenario employs direct mounting of an LTE paddle antenna (GE MDS PN: 97-2485A04) on the
Main and Aux Cell channels, and cabled mounting of the Wi-Fi antenna (GE MDS PN: 97-4278A34)
using a magnetic mount (GE MDS PN: 97-4278A78). This configuration offers easy mobility for
evaluation purposes or indoor applications with good cellular signal coverage (see Figure 10).

2. This arrangement employs cabled mounting of the LTE paddle antennas (GE MDS 97-2485A04) on the
Main and AUX Cell channels, and cabled mounting of the Wi-Fi antenna (GE MDS 97-4278A34)
using a magnetic mount (GE MDS 97-4278A78). The Wi-Fi antenna may also be directly attached to
the unit if desired. This configuration works well for indoor installations in equipment closets, or for
more permanent applications.
Outdoor use case:
External enclosures—If the system is going to be installed in a weathertight enclosure and mounted outside
in the elements, cabled use of external LTE antennas (GE MDS PN: 97-2485A05) on the Main and AUX
Cell ports, with cabled use of the External Wi-Fi antenna (GE MDS PN: 97-4278A48) is a good solution.
This configuration requires a suitable metallic ground plane for the Cellular antennas (8" diameter disc min-
imum for the 97-2485A05 series) or a suitable counterpoise for frequencies as low as 698 MHz. Metal
enclosures work well for ground plane requirements when ground contact inside the box is not impeded by
painted surfaces.
Do not use internally mounted antennas inside of metal enclosures.
Other antenna configurations can be easily customized for applications not listed here. Consult your factory
representative for installation matters.
