Procedure of installing the omnidirectional antenna on the roof 
2.9.4  Installation Procedures 
The installation procedures of installing omnidirectional antenna on roof show below: 
1)  Decide the installation location of the antenna according to the engineering 
design drawings. 
2)  Place the feeding point of the antenna facedown and the sheathing near the 
main supporting post of the support, then fix the antenna to the fixing bar of the 
support. 
  Caution: 
The top end of the sheathing shall be at the same height as or slightly higher than the support top. The 
transmission part of the antenna shall be higher than the top of the fixing bar. The fixing tightness shall 
be right enough for bearing and wind resistance. Looseness may cause loose connection while too 
much tension may damage the antenna sheathing
