ANTENNA CONSIDERATIONS
A variety of antennas is available from a number of quality suppliers. It is recom- mended you draw upon the advice of your Marine Dealer in determining a suitable
antenna for your vessel and range require- ments.
The general rules for antennas are: The more gain the greater the range and, the higher above the water line the greater the range. Antennas should be located so as not to be in proximity to metal objects. An-
tennas should not have excessively long coaxial feed cables.

CHOOSING.A'LQCATION
Some of the more important external fac-
tors to consider in selecting the location of your MC610 are:
1.Select a location is free from spray and splash.
2.Keep the battery leads as short as possi-
ble. Connection directly to the battery is most desirable. Ifdirect connection can-
not be made with the supplied power lead, any extension should be made with # 10 AWG wire. Long extensions should use larger wire.
3.Keep the antenna lead as short as possi- ble. Long antenna leads can cause sub- stantial loss of performance for both re- ceiving and transmitting.
4.Locate your antenna as high as possible and clear from metal objects. The reli- able range of coverage is a direct func- tion of antenna height.
5.Select a location that does not allow the radio to be subjected to direct sunlight (including that coming through win- dowsJ.
6.Select a location that allows free air flow around the heat sink on the rear of the radio.
7.Select a location well away from the ship"s compass. Auxiliary speakers also
should be located away from the com- pass.
Afteryou have carefully considered thevar- ious factors affecting your choice of loca- tion, position the radio (with the bracket, microphone, power plug, antenna plug
and any auxiliary plugs installedJ into the selected location to assure, there is no in-
terference with surrounding items. Mark the location of the mounting bracket.
Remove the bracket from the radio and use it as a template to mark the holes to be
drilled for the mounting hardware. Drillthe holes and mount the bracket with hard-
ware compatible with the material of the
mounting surface. Install the power cable (red is +, black
auxiliary cables and accessories.
Install the radio into the mounting bracket and connect all cables and accessories to
the appropriate jacks and connectors.
