1.0 or 2.4Ghz F Connector? - DirecTV

I need to replace the wall plate "F" connector behind my HR54 receiver in the RG-6 coax line connecting the receiver to the splitter/satellite. Does it matter whether the connector is rated for 1.0 Ghz or 2.4Ghz? Is one better than the other? I thought an installer once told me that the "barrel should be clear, not colored", seeming to suggest that it not be one of the newer 2.4Ghz connectors, which often have a blue colored barrel. Is this true?
