User's Manual

To ensure the best performance of the radio, the antenna cable

should be routed where it is least likely to interfere with, or

receive interference from other electronic equipment, such as

echosounder transducer cables and high current carrying

cables.

The antenna cable should terminate in a standard marine

PL259 plug ﬁtting. Connect the antenna plug to the socket on

the top of the transceiver unit and screw the retaining collar

down (Fig 7.17) -

RS87 VHF

Part No. E04297

NOTE To avoid possible water damage to the radio, it is recommend-

ed that the antenna cable is looped to provide a drip path.

7.4 Electrical interference suppression

Interference generated by the alternator of the engine may

occasionally cause problems. The RS87 has been designed to

minimise the effects of outside interference. However, precau-

tions should still be taken - route the power supply and anten-

na cables away from the engine compartment. The cable run

should not be down the same trunking as other cables carrying

high current. The antenna cable should also be kept separate

from the radio’s power cable.

Engines with spark ignition - and also some refrigerators -

should be ﬁtted with suppressors. Your local agent should be

able to give advice on this, and also supply suppression kits

where necessary.
