Cisco Indoor Swivel-mount Dipole Antenna (ANT-4G-DP-IN-TNC)
— A signal can penetrate five or six walls constructed of drywall or wood.
— A thick metal wall or wire-mesh stucco walls causes signals to reflect back and cause poor penetration.
Avoid mounting the antenna next to a column or vertical support that could create a shadow zone and reduce the coverage
area.
Keep the antenna away from reflective metal objects such as heating and air-conditioning ducts, large ceiling trusses,
building superstructures, and major power cabling runs. If necessary, use an extension cable to relocate the antenna away
from these obstructions.
CAUTION: Install the AP HWIC and any antennas away from appliances that share the same frequency bands. Microwave ovens,
cordless telephones, and security monitors can temporarily interfere with wireless performance.
CAUTION: We recommend you avoid installing wireless antennas in or near rack-mounted installations that include networking
equipment and computer servers whose radiated noise emissions can severely degrade radio performance.
NOTE: If the desired installation site has a marginally acceptable level of radiated noise emissions, consider using a
remote-mounted antenna, such as a wall-mount or ceiling-mount antenna, for better radio performance and coverage.
