Sennehiser beltpack Torx screw size?

Re: Sennehiser beltpack Torx screw size?

I need to replace an antenna on one of my Sennehiser IEM belt packs... does anyone know the Torx bit size?

The smallest I have is a T10 and its covers almost the entire head of the screw on the back.
Matt,
Did you find the right size? Also, I need to replace one as well, where did you get the new antenna?
