Feeder Antennas
The MR3000 incorporates dual feeder antennas, offering the security of dual path RF
redundancy. The last 31mm is the active portion of the antenna and should not be cut
or bent over the end of an antenna tube.
During operation the receiver switches between the two antennas. Locating the
antennas in different locations in the boat improves the ability of the receiver to see
the signal in all conditions.

Installing the Antennas
For optimum performance, mount the antennas in an orientation allowing the best
possible signal reception. Mount one antenna vertically up through an antenna tube
as high above the water line as practical. Mount the other antenna horizontally,
typically just under the edge of the deck, using tape to fasten the antenna in place.

Plugging In the Leads
Plug the servo leads into the appropriate servo ports in the receiver noting the polarity
of the servo connector. Note that the receiver features dual throttle and steering
outputs that allow dual throttles or dual steering servos.
