A system and method of adding hyperlinked information to a television broadcast. More particularly, the present invention relates to a method and to an apparatus for transmitting an SRS in a multi-antenna system. The anchoring unit is adapted for mounting by inserting the locking element into the receptacle, then rotating the contact element which is outside the receptacle and so that the locking element is initially restrained against rotation and then snaps into a locking position behind the shoulders on both sides of the receptacle. Once the retaining component is mated to the head or nut of the fastener assembly, the second portion of the device is releasably engaged with the neighboring structure.
