Not too in the way of specs for it, that could be my problem.
But I did find this http://www.wep4hams.com/base.htm that shows the one I
have.
Mine is the Workman T734 model.


Hi OM,

Well, it is a bit difficult to count the number of radial elements,
but it looks like between 6 and 8. Also, given that it operates from
25MHz (in an attempt to encompass the earth, sea, and sky) it must
ultimately disappoint you somewhere. That somewhere is that above 3
to 4 times the lowest frequency, those higher frequencies invest their
attention to sending/getting signals from overhead instead of out and
away towards the horizon. Also with fewer radial elements, there are
going to be gaps in SWR coverage (your reports confirm this).

Too often the Discone vendor is content to cite only the matching
characteristics and not mention that directionality explodes upward
like a wind swept umbrella. So, even if it did match to 2M, it would
tend to be deaf. Like I said, try to eliminate the top whip, and
retract the lower skirts lengths to roughly 1M length or less.
