Ok so I’ve had my electronics suite fitted , all very nice. Went out Sunday and struggled to be heard when calling up the nci for a radio check . I could receive no problem. Asked the installer about it today as all was perfect before the ais system was fitted. He told me that because the vhf now shares an antenna with the ais that is why the signal is weaker !!!! Does anybody know this to be true ?? I’m a bit miffed about it all and can’t understand why if this is a known issue they don’t tell you before purchase ! Thanks guys and gals !
