1.5  External roof antenna GSM/GPS   

 

The External roof antenna is used when the presence of an installation does not 
need to be hidden. The External roof antenna uses a rubber gasket to provide a 
watertight seal. With this antenna it is only necessary to drill one 18mm hole in 
the vehicle. The cabling for this antenna terminates with a male SMA connector 
for GSM and a female SMC connector for GPS.
