Mf Beacon Antenna - Veripos LD6 Installation Manual

Document title: LD6 Installation Manual
Document No. AB-V-MA-00520
3.3.3.2
It is recommended to disable the voltage on the L-Band connector when interfacing the
LD6 to a vessel Inmarsat system.
Damage may occur if the L-Band antenna voltage is set to "ON" in the MMI when
connected to an Inmarsat Communications system.
The voltage on the L-Band connection can be turned off using the LD6 MMI. Follow
instructions in the LD6 Operations manual (AB-V-MA-00521) to disable voltage output in
software.
An L-Band antenna will not function if the voltage is "OFF".
3.3.4
The installation of an MF antenna is determined by the use of an MF receiver card.
This section provides general guidance on the installation of an MF antenna.
3.3.4.1

The MF Antenna supplied may be a V86 antenna, identical to the L-Band Antenna.
However for use with MF only the antenna mounting requirements are different from
an L-Band antenna.

The antenna must be fitted with clearance from bulkheads and major metal
structures.

For MF use only it need not be mounted as high as other antennas as it does not
require line of sight to the MF Beacon signal source.

The antenna is supplied with an angle bracket and U-Bolts for mounting.

The antenna mounting point has a 5/8"x11 UNC Thread. As a result a mounting pole
can be used with the antenna if desired.
