1 Select one of the moulded bases and use the 3 M5 X
40 mm stainless bolts to attach it to the underside of
the dome. Note that the nuts are captive within the
dome assembly.
2 Insert 2 grub screws into the threaded bushes in the
base and tighten a few turns to hold them in place.
3 If the downlead is to be run inside the support tube,
follow steps 8 - 12 below.
4 If the downlead is to be run externally, screw the
waterproof ‘F’ connector on the cable supplied to the
outlet below the dome. Use a small 12 mm spanner
to gently tighten the sleeve which secures the
connector to the outlet. Caution, do not overtighten.
5 Mount the antenna on its support tube and lock
firmly in place by tightening the 2 grub screws in the
base using the 3 mm Allen key supplied.
6 Secure the downlead in place using cable ties or
similar. Caution, do not allow the full weight of cable
to be carried by the ‘F’ connector either during or
after installation.
7 As the down lead has been installed with the
waterproof ‘F’ connector at the top, it will be
necessary to fit the second connector supplied at the
injector end. Instructions for fitting this connector are
given in Diagram 3. Note that the spare ‘F’ connector
provided is not waterproof and should only be used
where protected from the weather.
8 To run the downlead inside the support tube, it is
necessary to open up the dome assembly. To do this,
first undo 6 Philips head screws and washers which
are located in recesses on the underside of the dome.
Then use 2 thin bladed screw drivers to gently prise
the 12 clip over portions at the circumference of the
dome lid outwards and upwards over the lip in the
dome base, until the two parts can be separated.
9 Cut the waterproof connector off the coaxial, run this
end up the tube and connect to the PCB saddle as
in diagram 1 and 2. Take care to avoid any whiskers
of wire from the cable shielding braid which could
short circuit the connections. Support the weight of
the coaxial by securing with the cable tie supplied.
The cable should be run to the location of the T.V.
receiver via the shortest route possible. Any excess
cable may be trimmed off then fit the ‘F’ connector
(supplied) to this end of the coaxial for connection to
the AE2000 Power Injector (supplied).
10 Clip the dome lid and base back together ensuring
that the tall spigot in the base locates inside the
hollow spigot in the lid. Replace and tighten the 6
Philips head screws and washers which hold the base
and lid together.
11 Mount the antenna on its tube and secure in place
by tightening the 2 grub screws using the Allen key
provided.
12 If further cable is added, this must be the same
type as supplied (75 Ohms RG 59 B/U) and a good
quality barrel (in line) ‘F’ connector, obtainable from
electronic hobby stores, should be used to make the
join. This connector will probably require sealing to
avoid moisture ingress and corrosion.
The short co-axial flylead with ‘F’ connector on
one end and PAL type plug on the other should be
installed between the ‘to television’ outlet on the
injector and the TV receivers antenna socket.
13 The amplifier in the antenna dome is powered by
the boat or vehicles 12 V DC supply injected into the
downlead by the AE2000 injector unit. Connect 12 V
from the boat or vehicle electrical system to the red/
black wire from the injector, red to positive (+) and
black to negative (-). Current consumption is 30-40
mA and this will run down batteries if left connected
for very long periods without charging. The antenna
system will not work if the polarity is incorrect.
A 500 mA fuse in the injector’s red wire protects
against short circuits in the downlead system.
When the antenna’s location has been decided and mechanical arrangements to support it have been made, final
assembly and connection of the downlead can be commenced.
