Install an omni antenna under a special environment
NOTE:
In Figure 20 the antenna pole is welded with two angle steels to the lightning rod pole, instead of a
cement pier.
Installing an omni antenna on the AP directly
To install a low-gain omni rod antenna directly onto the AP:
1.
Screw a feeder lightning arrester onto the downward 2.4-GHz antenna interface.
2.
Screw one end of the plug-to-plug adapter onto the feeder lightning arrester.
3.
Screw the omni rod antenna onto the other end of the plug-to-plug adapter. The omni
antenna should be at least one meter away from the pole or other metal objects.
4.
Ground the feeder lightning arrester with a grounding cable (see Figure 21 The outdoor
AP and the feeder lightning arrester are each equipped with a 3-meter-long grounding
cable. If the length is not long enough, acquire longer grounding cables. For the
grounding requirements, see ―Grounding and lightning protection.‖
