[Lowfer] Multicoupler

[David L. Wilson]

I have their HF model.  I noted it is easily opened, not potted, but used
surface mount components and the active component (IC) was unfamiliar.  It
works fine.  One of those failed some years ago and I have just today asked
about repair.  I have also ordered the VLF/LF mode.  

I regularly use their VHF/UHF models.

Sounds like you may have bought the Wellbrook loop antennas-everything
potted there but I figured out the power inserter by measuring across all
the external connections.
