[Scan-DC] Mystery Antenna Key Bridge

It’s been bugging me for years.  This antenna looks to me like a VHF, maybe marine antenna, which is mounted to the side of the Key Bridge at the Whitehurst Freeway.  The cable runs down the side of the bridge and then to???

Any ideas?  Is that for one of the boathouses?  But how did they get to attach it to the bridge?

Thanks,
Alan
