Safety precautions 

 

 

WARNING! 

 

Installing antennas is dangerous. For your safety, follow the installation directions. 

 

Keep the antenna away from power source, street lamps, distribution box, or other places that may 
cause electrical shock. 

 

Do not touch any power lines for your safety. 

 

 

Keep safety in mind when you select your installation site. Keep the antenna away from electric 
power lines and other lines. 

 

Do not work alone when you install the antenna. 

 

If you need to raise the mast, 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. 

 

If an accident, for example, electrical shock, occurs with the power lines, immediately call for 
qualified emergency help. 

Installation guidelines 

The ANT-2503C-M3 is designed to be mounted indoors on a ceiling to maximize its 

MIMO-omnidirectional propagation characteristics. 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-M3 is typically mounted indoors on the ceiling. Keep the antenna away from metal 
obstructions such as heating and air-conditioning ducts. Typically, the higher an antenna is above the 

ground, the better it performs. If possible, use a cable as short as possible to connect the antenna and 

AP. 

Mounting the antenna 

You can mount the ANT-2503C-M3 antenna on a ceiling by using bolts or a T-rail. The installation 

accessories are provided (installation tools are user supplied). If you intend to mount your antenna on 

another surface, you must provide the appropriate installation accessories. 

Tools and accessories required 

 

Accessories provided with the antenna for bolt-mounting: 

{

 

One paper mounting template 

{

 

Two M6 bolts  

{

 

Two M6 hex nuts
