Page 9: Introduction
Initial inspection Introduction 1 Introduction This manual provides instructions for installing a TT-3005M Maritime Antenna. Figure 1.1 TT-3005 Maritime Capsat Antenna Initial inspection Inspect the shipping carton immediately upon receipt for evidence of mishandling during the transit. If the shipping carton is severely damaged or water stained, request that the carrier's agent be present when opening the carton. -
Page 10: Storage
Storage The TT-3005M may be stored or shipped in temperatures within the limit -40° C to 80° C. It is advisable to protect the TT-3005M from extreme temperature variation, which can cause excessive condensation. It is recommended that the TT-3005M is unpacked immediately on delivery. - Page 11 Repackaging for shipment Introduction 4. Seal the shipping container securely. 5. Mark the shipping container FRAGILE to ensure careful handling. 16Aug06 Page 1-3...

Page 13: Description
Description Description Figure 2.1 TT-3005M Maritime Antenna The TT-3005M is an omni-directional antenna with built-in LNA/HPA electronics designed to operate on vessels. The antenna housing is sealed and contains no user serviceable parts. The antenna is very compact and is designed to operate in a corrosive environment and in extreme weather conditions without any service. - Page 14 This antenna can handle 32 Kbytes transmission length and up to 100 meter coax cable. The TT-3005M antenna is designed to operate when the satellite is visible over the horizon and no signal path blockage is present. The TT-3005M antenna is equipped with a TNC female connector and with 1’’...

Page 16: Safety Distance For Antenna Unit
Description Safety Distance for Antenna Unit The safety levels for the Thrane & Thrane INMARSAT-C Antenna Units are based on the ANSI standard C95.1-1982 "American National Standard Safety Levels With Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 300 kHz to 100 GHz" This standard recommends the maximum power density at 1.6 GHz exposed to human beings not to exceed 5 mW/cm². -
Page 17: Installation
Installation 3 Installation This chapter provides specific information enabling you to install the TT-3005M Capsat Antenna into your own system, with a minimal effort. Transceiver Configuration This new antenna is designed to use a very low amount of power. To ensure that the transceiver detects the antenna as connected the voltage output of the transceiver has to be reduced. -
Page 18: Mounting Considerations
Installation Figure 3.1 TT-3005M 1’’ Tube Mounting Is is important to notice that the pole mount device has to be disconnected from the antenna body when the antenna cable should be mounted. It is not possible to mount the cable without dismantling the pole mount. - Page 19 Installation Distance to HF antennas > 5 m Distance to VHF antennas > 4 m Distance to magnetic compass > 3 m The antenna is designed to provide satellite coverage even when the vessel has pitch and roll movements up to 15°. To maintain this coverage the antenna should be free from obstructions in the area down to 15°...
- Page 20 Installation Zenith Horizon Horizon Obstructions should be below these Figure 3.2 Inmarsat-C Antenna Mounting If an obstruction such as a pole or a funnel is unavoidable, the following guidelines apply: The distance to the obstruction should be so large, that the obstruction only covers 3 degrees.
- Page 21 Installation Obstruction is a 4" pole. Diameter = 0.1 m. Safe distance is 20 * 0.1 m = 2 m Max obstruction angle 3 degree Figure 3.3 Inmarsat-C Antenna mounting near pole or funnel 16Aug06 Page 3-5...

Page 22: Antenna Cable
Installation Antenna cable The TT-3005M Antenna specifications requires that the total maximal attenuation at 1.65 GHz must be less than 17 dB, and the maximal total (short-circuited in one end) DC resistance must not exceed 0.7 Ohms. In case the antenna cable is to be produced on site, the cable...
