When a Manager Gateway is mounted in a location
that is shielded or that attenuates radio frequency
communications, the optional antenna kit may need
to be used. Use the antenna and cable in place of the
standard antenna.

The Manager Gateways is designed to operate with the
antennas listed below that have a maximum gain of 2 dB.
Antennas and cables not included in this list or having a
gain greater than 2 dB are strictly prohibited for use with
this device. The required antenna impedance is 50 ohms.
Antenna included P/N 283189: ½ wave, 5”, 2dBi antenna
Optional antenna kit P/N 185519-01: 2.4Ghz, 12”, 6dBi,
antenna with 75-ft, 50 ohm cable (must be used together
to meet maximum antenna gain. Do not modify the
cable).
To reduce potential radio interference to other users, the
antenna type and its gain should be so chosen that the
equivalent isotropically radiated power (e.i.r.p.) is not
more than that permitted for successful communication.
The antenna used for this device must be installed to
provide a separation distance of at least 20 cm from all
persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
