INSTALLING THE ANTENNA
Owing to the low frequency nature of the signal, it is not necessary
to mount the antenna at a great height. However many types of
electrical apparatus emit interference and it is important that the
antenna is well clear of such interference. Troublesome items are
alternators, ignition coils, motors, strip lights, inverters etc. Select a
position as far from likely sources of interference as is practical
and mount the aerial using the flange on the base. Ensure that the
antenna is at lease 30cms from other metal structures that are parallel to it.
A pushpit mounting bracket is available from your chandler, or
Nasa Marine spares department. The bracket permits the antenna
to be mounted to any 25mm diameter horizontal rail.
Run the antenna lead back to the receiver. The cable can be
shortened or lengthened using standard 75 ohm coaxial cable.
Take great care when making connections. Power for the
active antenna is supplied by the coax so all joints should be
soldered and properly insulated. Alternatively a 7 metre
extension cable is available from your chandler, or Nasa
Marine spares department.
INSTALLING THE DISPLAY
The Target navtex is not waterproof and should only be cabin
mounted. Select a convenient position for the display, secure
the mounting cradle with two screws and fit the navtex into the
cradle using the side knobs supplied.
