    Water-Resistant Wrap Terrasat recommends applying water-resistant wrap (such as mastic tape) to all outdoor connectors to prevent water entry 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 tape forms a tight, continuous coating that permits little or no moisture absorption or penetration.

    • Electrical Grounding Grounding the IBUC 3, IBUC 3G and PSUI units is recommended to prevent possible damage from lightning and/or other induced electrical surges. Terrasat recommends that 3/0 or 4/0 AWG (American Wire Gauge) stranded copper wire be used to bond the IBUC and the PSUI to the earth ground (grounding rod), using the most direct (or shortest) route.

    Tx Power Alignment Transmit L-band Input Adjustment with Modem or Converter WARNING DC power might be present on the cable. Terrasat recommends the use of a DC block. To set the power level of the modulator output: 1. Use a spectrum analyzer to measure the power level of the L-band signal at the output of the coaxial cable that connects to the Tx 1+1 interface module at J2 (Tx L-band).
