Cisco Cisco Aironet 3500e Access Point 데이터 시트

Cisco recommends a high-quality, low-loss cable for use with the antenna.

Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. 
The cable should be kept as short as possible because cable length also determines 
the amount of signal loss (the longer the run, the greater the loss). 

Painting the antenna and the bracket does not affect its performance if you use 
standard exterior-grade, oil-based or latex paint. Do not use metallic or 
metallic-flake paints, which will degrade antenna performance.

Before painting the antenna, cover the vent on the back of the antenna with 
masking tape to prevent clogging (

).

Cisco recommends Krylon Fusion for Plastic or Rust-Oleum for Plastic (which 
might require a primer coat). For best results, follow the surface preparation 
suggestions from the paint manufacturer.
