8.4 Environmental Usage/Concerns

8.4.1 Choosing an Antenna/Cable to Meet Application Exposure Conditions

There is no antenna or cable design impervious to every environmental condition it could be exposed to. Review
the application environment as follows:
Step 1 Determine where the antenna will be installed and the application conditions: indoor, outdoor, or limited
outdoor exposure. Even if the antenna is going to be used indoors, an outdoor antenna may be more
suitable (i.e., resistant to fluids, rigid construction, etc.)
Step 2 Determine what the antenna may be subjected to (i.e., fluids, chemicals, oils, wind, shock, vibration, etc.)
Step 3 A. Review antenna and/or cable materials (listed in Section 8.1) with respect to resistance of
chemicals and fluids in the application. If choosing an adhesive mount, adhesive resistance
testing may be necessary.
B. If shock, vibration, wind, rain, sleet/snow, etc. are in the application, choose an antenna rated for
outdoors and has a rigid design as defined in Sections 8.1 and 8.3.3.2.
Step 4 This step may be required to provide an extra level of protection, especially if the application may be
subjecting antennas and cables to liquids. The RP-SMA connections, tilt/swivel joints, and cable
entrances are potential leak paths that could lead to corrosion. The following procedure is one way to
provide extra protection to these connections and joints.
Ensure the area applying tape to is clean from contaminants by first cleaning it with mild detergent/water
and completely dry. Follow with an isopropyl alcohol wipe of the area.
Layer 1: Wrap a layer of polyvinyl chloride insulating tape
Layer 2: Wrap a layer of rubber splicing tape i.e. Scotch™ 23
Layer 3: Wrap a layer of UV stable polyvinyl chloride insulating tape
Layer 1 allows the user to remove Layer 2 for connector inspection, antenna replacement,
repositioning of the tilt/swivel antenna, etc.
In the end, the antenna/cable choice may need to be tested in the actual application conditions to prove suitability.
