Antennas and Wireless

To get the best performance, this second antenna should be placed at a minimum of 5/8 of a wave length away

from the other antenna. Therefore, the minimum spacing for antennas in the 800 MHz frequency is 5/8 * 13.5"

= 8.5". The diversity antenna can be spaced further away than this, ideally in increments of 13.5", 22", 35", etc.

For a 1900 MHz only network, the optimal distance would be 5/8 * 6.2" = 4". Orienting the antennas differently

from one another may also improve performance, particularly when the antennas are close together.

• GPS: This unit uses an active antenna only. It is used for receiving signals only. Please refer to the Red Lion

website

for information on GPS antennas.

• Wi-Fi: A reverse-SMA (female) connector is provided on the RAM-9x3x units that include Wi-Fi connectivity.

Please use a 50 ohm cable and antenna that are rated for Wi-Fi connectivity per IEEE 802.11b/g/n. Please refer

to the Red Lion

website

Per FCC requirements the antenna gain including cable loss must not exceed 7.5 dBi in the Cellular band, 3 dBi in

the PCS band, 5.5 dBi for LTE Band 4, and 9 dBi in the LTE Band 17 for RF exposure purposes of 2.1091. The

antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all

persons. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any

other antenna or transmitter except in accordance with FCC multi-transmitter evaluation procedures.
