13.3 RLX2-IHx Approved Antennas
If you are located In the U.S. and Canada, use antennas that are specifically approved
by the U.S. Federal Communications Commission (FCC) and Industry Canada for use
with the RLX2-IHx series radios. Contact ProSoft Technology or visit
for a current list of approved antennas.
Antenna selection depends on whether the bi-directional amplifier is being used or not.
For each approved antenna, there is a specified minimum distance the antennas must
be separated from users for safe exposure limits, according to FCC part 2.1091.
13.3.1 Approved Antenna Table
Use the following approved antennas when the RLX2-IHx series radio module is
connected directly to an antenna. See Approved Antennas with Power Amp (page 226)
for a table of approved antennas with bi-directional power amplifiers.

13.3.2 Approved Antennas in Europe/CE
In Europe/CE, the gain of the antenna connected to the RLX2-IHx series radio main
antenna port, minus the antenna cable loss, must be less than 4 dB to stay below the
100-mW EIRP transmit power limit.
The AUX port on the radio is only used to receive; it never transmits.
Note: In France, the user is responsible for ensuring that the selected frequency channels comply with
French regulatory standards. At the time of this printing, only channels 10 through 13 can be used in
France.
