Remote external antennas: PCTEL/MAXRAD P/N MFB9380 (Tessco P/N 61900) for unity gain (2.15 dBi);
PCTEL/ MAXRAD P/N MFB 9153 (Tessco P/N 74300) for 3 dB gain (5.15 dBi)
There are several options for remote antenna cabling. The most economical connection to the external
remote antenna is the LMR-400 type cable. This type of cable is suitable for distances up to 100 feet
(approximately 30 meters). Antenna cables should be ordered with the N-type male connectors on
each end. One end attaches to the gatekeeper housing, and the other end attaches to the antenna.
You can perform on-site assembly or order pre-assembled cables (for example, from Laird
Technologies).
WAN communications
The EA_Gatekeeper model 2210 is equipped with an Ethernet communications option board. This
option board is connected to an internal Ethernet surge suppressor. The external Ethernet device cable
is routed through the Ethernet cable gland and connected into the bottom of the Ethernet surge
suppressor. The cable used must be rated for outdoor use, have a minimum CAT 5 rating, and have
EMI/RFI shielding with conductive RJ-45 connectors. The cable shielding is connected to ground on the
EA_Gatekeeper side and should be left ungrounded on the external equipment side to prevent a
ground loop scenario.
Placing the EA_Gatekeeper model 2210 into service
Use authorized utility procedures when installing the EA_Gatekeeper model 2210. Dangerous
voltages are present. Equipment damage, personal injury, or death can result if authorized utility
procedures are not followed when installing the EA_Gatekeeper.
The EA_Gatekeeper model 2210 is a FCC Part 15 Class A device, and it is not intended for installation in
or on a residence. See the FCC Part 15 Class A compliance statement on page 9.
Be sure to properly ground the EA_Gatekeeper before placing the gatekeeper into service.
