For best reception the Dome antenna should be installed as high as possible clear of metal objects such as masts, stays or
antennas, etc., which may distort the omnidirectional pickup pattern. It should not be in the line of fire of radars.
On vehicles, the dome should be mounted as high as possible above the roof. 100mm (4 in) should be used as a minimum guide.
Flush mounting is acceptable on a fibreglass roof. On ships using high power transmitting equipment the Dome should be
mounted as far as possible from transmitting antennas. Mounting may be by U bolts or hose clips clamped to a stub mast or other
structure or via the threaded flange mount provided.
The cable must be securely supported so that the cable weight does not hang on the dome connector. The cable may be
shortened or lengthened as required. To avoid ghosting, extension of the cable should be made by using an “in line” good quality
75W cable connector and 75Ω cable, preferably the same type as supplied with the antenna. All connections must be sealed to
prevent moisture ingress, particularly the coaxial connection in the base of the antenna. Use sealing tape provided.
The dome mounted amplifier is accessible by removing the 6 screws securing the cover plate on the base of the dome. The
amplifier connections and cover plate are sealed with a neoprene gasket and must be removed carefully. Do not open it unless
there is a problem. Service of the amplifier/control unit should only be carried out by a qualified technician. Replacement amplifier
units are available from Moonraker. When replacing the amplifier it must be resealed again, using grease such as petroleum jelly
on both side contact edges of the gasket. If using silicone, it is most important that only neutral cure silicone sealants are used as
other types corrode metals.
The control unit may be mounted in any convenient position located inside the vessel. For the AM/FM unit, mounting holes are
accessible by removing the unit lid. Connect the control unit battery cable to a suitable DC system. Wire with tracer is positive.
The unit will not work if polarity is reversed. If 110 or 240 volt AC operation is required use a 12 volt DC plug pack with a current
rating of at least 100 milliamps.
Power for the Dome amplifier is fed via the coaxial connecting cable. In the TV AM/FM control unit short term protection against
cable short circuit is provided by a fuse in the control unit, but long term short circuit may cause control unit overheating. The TV/S
unit’s fuse is external in line. Cables from control unit to receivers should be 75Ω and as short as possible.
If a dual AM/FM vehicle type receiver is fitted, special low capacity cables should be used for connection to the AM antenna. This
does not apply if the Moonraker 15BC receiving antenna is used. Both control units are reverse polarity protected. Coaxial cable
connection details are shown above.

3. Slide on the connector, leaving 1.5 to 3mm of the centre conductor
protruding. The dielectric should also be flush with the bottom of the nut.
Then crimp the connector.
