Only the IFI engineers can say for sure, but if you have a transmitter
and a receiver close enough in frequency that the transmitter causes
the receiver interference problems, you can put them on different
antennas and position the antennas to minimize the coupling between
the transmitter and the receiver.
Given that there is an antenna out of sight in the radio modem case
it is very important that the modem be mounted well clear of any metal
structure on the robot. We mount our antenna on a piece of polycarbonate
a good distance away from metal structure on the robot and have not
had any problems with the radio, but we will be first in the line to upgrade
the radio firmware, and install V15 of the master code, at Portland.
