Recommendation to choose installation location as below; 

z

  Use proper and reliable connectors. 

z

  Ensure that connections of antenna and feeder cable is proper, so that 

antenna VSWR is at least 1.38 : 1(equal to 16dB of return loss). 

z

  Ensure that antenna radiation beam pattern is normal before antenna 

installation. There are cases that antenna beam pattern is abnormal though 
antenna input VSWR is normal and this problem cannot be recognized with an 
Analyzing Equipment. 

z

  Secure and water-tight connection between cable and antenna. 

z

  Cables with low loss. 

z

  Elimination of pulling stress or kinks in cable. 

z

  Proper radius of curvature in cable placement. 

z

  Secure proper isolation between link antenna and service antenna. 

z

  There must not be any obstacles to reflect signal from the direction that 

antenna is radiating signal. 

z

  Tightly fix link antenna to prevent movement against wind or other external 

factors.
