Safety precautions
|
|
WARNING! · Installing antennas carries some level of risk. For your safety, read the following safety precautions carefully before your operation. · Keep the antenna away from power sources, street lamps, power distribution boxes, or other places that might cause electrical shock. · Do not touch any power lines for your safety. |
· Keep safety in mind when you select your installation site. Keep away from electric power lines and other lines.
· Do not work alone when you install the antenna.
· If you need to raise a post, work with other people to avoid bodily injury.
· Do not use a metal ladder. Do not work on a wet or windy day. Dress properly, for example, shoes with rubber soles. Wear rubber gloves.
· If the antenna, antenna cable, or any other installation accessory drops, get away from it to avoid bodily injury.
· To avoid any potential hazards, always have a professional handle power connection rather than attempting it yourself.
· If an accident, for example, electrical shock, occurs, immediately call for qualified emergency help.
Installation guidelines
The ANT-2503C-S is designed to be mounted indoors on a ceiling to maximize its omnidirectional propagation.
Install multiple antennas where necessary because doors, windows, and walls degrade signal quality.
Keep the antenna away from metal obstructions and wire mesh.
Choosing a mounting location
The ANT-2503C-S is typically mounted indoors on the ceiling. Keep the antenna away from obstacles and metallic objects such as heating and air-conditioning ducts, large ceiling trusses, and primary power transmission systems.
Typically, the higher an antenna is above the ground, the larger the signal coverage area.
If possible, use a cable as short as possible to connect the antenna and AP.
Mounting the antenna
You can mount the ANT-2503C-S antenna on a ceiling. The installation accessories are provided with the antenna (installation tools are user supplied). If you intend to mount your antenna in a way other than what is described in this document, you must provide the installation accessories yourself.
Installation tools
The following tools are required for installing the antenna
· One electric drill and drill bits
· One adjustable wrench
Mounting the antenna on a ceiling
1. Drill an 18 mm (0.71 in) diameter hole in the ceiling where you want to mount the antenna.
2. Remove the flat washer from the antenna and place it above the ceiling.
3. Thread the antenna cable through the hole you drilled in step 1 until the antenna is flush with the ceiling.
4. From above the ceiling, slide the flat washer down onto the antenna’s thread and fasten it until the antenna is secured in place.

Recommended cable
As a best practice, use a high-quality, low-loss cable with the antenna. Coaxial cable loses efficiency as the frequency increases, causing signal loss. Keep the cable as short as possible because cable length also causes signal loss (the longer the run, the greater the loss).
