I tested the antenna using two adapters to get from the UHF male of the antenna itself to an N female. But likewise, I don't like using adapters, especially high up on a tower where it's not easy to get to.
The part is labeled (stamped) as follows: 50896 0410-25 The stamping looks just like an Amphenol or Kings style marking. I tried to search Ampenol, King, and a few others, but can't seem to locate the OEM mfg. Anyone recognize the number above to decipher who the OEM is?
