A DB-1015 does not have an 18 foot boom, and it has 3 elements only. It's a
really tiny antenna.
I don't know about the TH-4 but I had an old TH-3 and the hardware was not
what we think of as "modern day HyGain." If it has "modern day HyGain"
hardware, then it is undoubtedly a HyGain, unless someone at some point
cobbled together an antenna. Do you have any photos of it you could post,
