This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
(1) this device may not cause harmful interference and
(2) this device must accept any interference received, including
interference that may cause undesired operation.
Cable Length Requirements
To meet Iridium performance requirements and comply with FCC
regulations, care must be taken to use the appropriate total RF cable
length. Your antenna distributor should provide the appropriate cable.
WARNING
To satisfy FCC RF exposure requirements for mobile transmitting devices, the minimum safety distance is 55 cm (21.7 inches). This
separation distance should be maintained between antenna and people during operation of the antenna.
Changes or modications not expressly approved by Beam Communications could void the users authority to operate the
equipment or the warranty.

Introduction
The RST740 antenna is designed for Iridium applications where
long RF cables are needed and a passive antenna cannot
be used. The RST740 has an integrated power amplier (for
transmitting signals to the satellite) and low noise amplier
(for receiving signals from the satellite) incorporated into the
antenna.

Important Safety Information

1. Bring the long RF cable to the top of
the pole or mast.
2. Feed the cable though the
mounting bracket and attach the
TNC connector to the antenna.
3. Insert the Mounting Screws to
fasten the mounting bracket to
the antenna.
4. Place the mounting bracket over the
pole and tighten the set screws.
1. Attach the Type N connector from the long RF cable
to the bias box.
2. Attach the short RF cable to the bias box and the
docking station
3. Connect DC power (9 to 36 VDC, 30W) to bias box.

WARNING:
Do not place the antenna anywhere there is a

WARNING
Galvanic Corrosion Protection
This antenna has a base and pipe adapter is constructed out of
aluminum. When the antenna is mounted to a steel mast or metallic
bracket, a galvanic reaction can occur resulting in aluminum
corrosion. To minimize corrosion the following steps can be taken:
• apply self-fusing silicone tape to all connectors
• use a UV-resistant, non metallic mast when possible
• apply silicone grease or joint compound do all metallic
surfaces that make contact with the antenna or mounting
adapter
• if possible use an insulating plastic or rubber sleeve between a
steel mast and the aluminum adapter.
Antenna installation is critical for optimum performance of your Iridium service.
Installation Guidelines
To ensure maximum performance of the antenna system and to
maximise availability and reliability of service the antenna must;
• have a clear line of site to the sky
• be clear and free of obstructions
• be clear of metal objects
• be located away from other transmitting devices
• be securely affixed in location
• not be located indoors
• be installed in conjunction with a certified cable
Installing Antenna Cables
When installing antenna cables, follow these guidelines:
• Route and restrain cables to prevent them from vibrating or moving
under normal conditions, which could result in damage to the
antenna or the coaxial cable connections.
• Wherever the cables contact structures, protect the cables from
chafing or abrasion. If a cable needs to be bent, avoid kinking it, and
ensure that each bend radius follows the cable supplier limits.
• Use coaxial sealant, shrink-wrap tubing, electrical tape, or another
suitable product to seal all cable connections appropriately to
prevent moisture and corrosion damage from weather exposure.
• Mount all antennas vertically and clear of nearby metal obstructions
• Minimize horizontal obstructions as much as possible because they
can create areas of poor system coverage.
Installation Options
The antenna system is suitable for marine and fixed applications and
is designed to meet Iridium System performance requirements when
installed according to the instructions in this guide.
NOTE: This cable is not part of the antenna kit.
