This document details the installation of a Remote Antenna Kit with the Lantronix LEO-I Kit. A remote antenna can be used in situations where the Above Deck Unit's (ADU) built-in antenna is insufficient or if the Above Deck Unit cannot be mounted in a position with clear line-of-sight.
The remote antenna kit should contain:
Disconnect the existing SMA cable from the Iridium modem (ANT).
Connect one end of the new SMA to SMA cable to the Iridium modem (ANT).
Connect the other end of the SMA to SMA cable to the top of the N-type connector at the bottom of the ADU.
Connect the LMR-400 cable to the external side of the N-type connector at the bottom of the ADU.
Connect the LMR-400 cable to the external Iridium antenna.
Mount the antenna in the desired location.
IMPORTANT: Make sure to match up the correct holes when screwing into the antenna mount. The below pictures show which holes to use.
Mount the antenna using 4 each # 6-32 x Â¼" Stainless Steel screws (supplied).
