INSTALLATION
GEN ERAL
1 This section provides installation information for SharpEye
TM
X-band Upmast
Transceiver.
2 Kelvin Hughes, or appointed agents, contracts only to supply the equipment, supervise
the installation and final connection of the equipment. The installation must be made by a
fully qualified Kelvin Hughes Radar Engineer.
3 Forward planning for positioning the various units of the Radar must be made before any
installation work is carried out. A full survey is required in order to establish the ship’s
fitment. This may be arranged with the Technical Department of Kelvin Hughes or one of the
approved agencies. Details of Agencies worldwide can be found in Publication KH 401.
COM PASS SAFE DIS TANCES
4 Compass safe distances are stated on labels on all units and are as follows:
Standard Compass Limit Steering Compass Limit
5.4°/H 18°/H

TRANS CEIVER
5 One version of upmast transceiver is available, type DTX-A3, which is used with the
Low Profile Antenna (LPA) (LPA-A25).
6 The transceiver is used with a bulkhead mounted Drive Control Unit (GTX-A24), which
provides the 3-phase power for the antenna turning motor.
