Barjan is a Distributor, not necessarily a manufacture of everything or anything they sell.
Most of your CB antennas and mic manufactures have been bought by Barjan as you may well know, like Wilson antennas, Francis antennas, and Astatic mics, etc.
Many of these products still look the same and still have the OEM brand name as before, I suspect most of these products are still being made in the same manufacture plants most likely overseas and made to the same spec's so there might not be any difference except in one's head because of the Barjan stigma.
