Remove a link from Signal

Hi all,
So I was fiddling around with the RCAP signals and I inadvertently, and to my surprise made a gantry mount signal mast with no signals. Which is something I have always wanted to do but couldn’t figure out how to do it. So…now that I have it, it still thinks signals are attached to it (although not visible) so how can I make it just a scenery object for use with the signal gantry? Also…is anyone familiar with the matrix in the bottom of the xml files? Does this allow you to put multiple heads on different mounts? I would love to mix heads so I can get configurations that aren’t already in the initial RCAP files.
