Clean the u7 antenna
Prior to cleaning any part of the u7 antenna, ensure it is powered off.
General cleaning
Blow or rinse off loose debris first, and then apply a cleaning agent and use a clean, soft towel to clean the stained area.
Avoid scrubbing and do not use abrasive materials when cleaning the terminal components.
Avoid exposing rubber parts (for example, gaskets) to alcohol or alcohol-based cleaners, for these can deteriorate the
rubber.
General cleaning agents
Clean fingerprints, smudges, salt spray, and light marks with isopropyl alcohol products (CAS Number 67-63-0). It is safe
to use isopropyl alcohol on the antenna.
Clean difficult stains, such as oil, grease, soot, ink, and other soils with LPS Precision Clean Multi-Purpose Cleaner
Degreaser at 10 to 1 dilution.
Connectors
Use a soft bristle acid brush or cotton swab with isopropyl or denatured alcohol to gently clean all connectors. Take extra
care when cleaning RF air-dielectric connectors and don’t damage, bend, nick, push in, or pull out the center connector
as this can affect your signal. Carefully clean any surface corrosion on the exterior of the connector. Do not scrape or
overscrub the connector as this can damage the connector coating and render it more susceptible to corrosion.
Ensure connectors are completely dry before reconnecting.
Screws
Use a soft bristle brush and isopropyl or denatured alcohol to clean lightly oxidized screws. Replace heavily corroded or
oxidized screws when possible. For information on replacing parts and components, see
