Antenna (optional)
Note This step is optional if you do not want to use the on-vehicle gust-air radio system.
MX400 is optimized for co-existing of multiple radio systems. Two antenna racks allow mounting of
external antennas with different shape and size.
To install, attach the antenna onto the surface of the rack, and tightening it using nylon fastener tape, as
shown in figure 5, 6, and 7.
