Commercial Loopstick Antenna Manufacturers?

I am an electrical engineer working on a product that needs a loopstick antenna.

I had thought that AM radios were so commoditized that I’d be able to find an off-the-shelf vendor. However the closest thing I found was a recommendation in silicon labs AN602 app note for some shady Chinese company.

Can anyone point me to a reliable supplier that I could purchase from in quantity? I have familiarity working with magnetics suppliers to build custom magnetics but was hoping to avoid that route.
