IsoMatch Global GPS antenna.

Warning! 

Improperly installed cables near machinery can be dangerous.

IsoMatch Global GPS antenna placement

Placement of the IsoMatch Global GPS antenna is crucial to the system’s operation. The GPS inside the 

antenna computes a position based upon measurements from each satellite to the internal GPS anten-

na unit. Mount the IsoMatch Global GPS antenna on your point of interest.

Please make certain that there is an unobstructed view of the sky avaiable to the IsoMatch Global GPS 

antenna, when choosing a mounting location. 

This will ensure that the GPS satellites are not masked by obstructions, which can potentially reduce 

system performance.
