3-18 | Cyber Hardened IBUC 2, IBUC 2e, IBUC 2G, IBUC R, IBUC G Operations Manual: Installation
Cable and Waveguide Connections
When installing the cable and waveguide assemblies, ensure that all connections are
weather tight. If an Rx reject filter is being used, attach it to the IBUC waveguide
output. Use proper gasketing methods to prevent the entry of water.
Water-Resistant Wrap
Terrasat recommends applying water-resistant wrap (such as mastic tape) to all
outdoor connectors to prevent the entry of water and subsequent water damage. Mastic
tapes are designed to flow and self-heal if cut or punctured. When applied spirally with
the proper tension, mastic tapes form a tight continuous coating that permits little or no
moisture absorption or penetration. Terrasat provides water-resistant sealing tape for
Type-F and Type-N connectors.
Apply the mastic tape, as follows:
1. Ensure that all connectors are firmly tightened, dry, and free from all grease, dust,
and dirt.
2. Cut the mastic tape to the desired size. The tape should be long enough to cover the
connector completely.
3. Center the tape on the connector to be sealed and wrap the tape in a tight spiral
around the connector using a 50% overlap. Squeeze the tape tightly and ensure that
both ends of the tape have formed around the connector and the cable with any
gaps.
Apply the tape to all connectors that may be exposed to moisture.
Applying the Anti-Seize Lubricant
Terrasat recommends applying anti-seize lubricant to screws and bolts that could be
exposed to weathering or corrosive environments. The lubricant prevents galling,
seizing, and corrosion during assembly and aids in future disassembly. A 5 g pouch of
Permatex anti-seize lubricant is included with the installation kit for this purpose.
Ensure that all power is disconnected prior to making any connections.
