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.

• Iridium antenna (the "external" antenna)
• Black antenna mount
• 10 ft LMR-400 cable
• 12" SMA to SMA cable
• Stainless steel plug

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.
