Consider the following guidelines before you install the GNSS antenna:
RF site survey for antenna location
RF environment details, such as transmission source and proximity
Grounding plane
Cable routing
We recommend the guidelines and procedure described in this chapter to ensure optimum
GNSS signal reception for the ACX500 router.
