2.2.3 

Mounting Considerations 

When mounting an antenna, care should be taken to make sure it is as far away from metal objects as 
possible. If nearby metal gets too close to an antenna, it has the potential to interfere with the way the antenna 
radiates and may cause some undesirable results. 

In some cases, a cable must be used to connect an antenna to a transmitter or receiver. All RF cables add 
some loss to the system. For any given cable, the longer the cable the more signal will be lost over that cable. 
Because of this the length of the cable should be kept as short as possible. Often a longer serial cable can be 
used to minimize the length of the antenna cable. 

If you have two (2) wireless modems, you do not have to configure the modems and you may 
proceed  with  the  installation  instructions;  the  modems  are  pre-configured  for  two  (2)  or  less 
modems.  

If  you  have  three  or  more  wireless  modems,  please  refer  to  page  26  for  setting  up  multiple 
modems.
