C.9.3 Isolation of the antenna from the mounting base 

In cases where the antenna is to be isolated from the mounting base, shoulder 
bushes and washers (accessories) must be used as illustrated below. Please 
note that the isolation has to be implemented on all four mounting bolts 
(including the bolt securing the ground cable).
