this oddity is sitting on the roof of my friends apartment building, unused as far as we can tell. I took the pic through the skylight as we don't have roof access. I'm thinking it could be some old school tv antenna for multiple unit apartment buildings circa 1960s? but of course i'm hoping it's really something of use to a ham. Any ideas ?

edit: to give some perspective the larger beams on the right side are about 6 to 8 feet.

It is a TV antenna.  Might work for 6 meters.  I believe this might be a Telrex antenna

Those are both early TV antennas for relatively local work.

One is sort of a dual phased Vee-beam.  The other is multiple dipoles in front of a reflector.

In fact, both those antennas are described on page 24-14 of Jasik's Antenna Engineering
Handbook
, published in 1961, complete with plots of gain vs. frequency for the TV bands,
in case you want further information.

yeah i figured it must be for TV, maybe there's a useful mast in place already at least. Thanks!
