Remote Antenna (Optional)
The remote antenna options provide flexibility for mounting the Gateway based on wireless
connectivity, lightning protection, and current work practices.
Remote mount antenna kits include weather proof tape for use on the cable connections,
and a mounting kit for the lightning arrestor and antenna. The following diagram and table
describe each remote antenna kit option.

WARNING
When installing a remote mount antenna for the Smart Wireless Gateway, use
established safety procedures to avoid falling or to avoid contacting high-power electrical
lines.
Install remote antenna components for the Smart Wireless gateway in compliance with
local and national electrical codes and use best practices for lightning protection.
Before installation, consult with the local area electrical inspector, electrical officer, and
work area supervisor.
The Smart Wireless Gateway remote antenna options are specifically engineered to
provide installation flexibility while optimizing wireless performance and maintaining local
spectrum approvals. Each remote antenna kit contains 50 ft. (15,2 m) of LMR-400 coaxial
cable, and a high-gain antenna. To maintain wireless performance and avoid
non-compliance with local spectrum regulations, do not change the length or type of
coaxial cable, or the antenna type.
If the remote antenna kit as specified is not used in this document, Emerson Process
Management is not responsible for wireless performance, or non-compliance with local
spectrum regulations.
