Who knows what that might imply relative to this antenna. After getting my refund, I sent the seller a message saying that I would buy another if he could assure me it would work at 12 volts. He replied that he needed to get his hands on a couple and do some testing first. The antenna that I received seems to be different to the one pictured in the eBay listing. At least the labels are different. I get the feeling he is kind of a third party dealing with someone in China who is wholesaling antennas made by someone else. Who really knows what spec. these are made to, or by who. In my former place of employment, we made an SMB terminator. Basically, a 75 ohm resistor soldered across the pins of an SMB connector, then molded in black plastic. We bought the connectors from a Chinese supplier who supplied them in individual plastic bags. We had to cut the parts out of the bags before processing, which added a labor step. We tried to get the supplier to sell them to us packaged in bulk, but they refused. We decided that they were actually buying them from someone else and just doing a passthru. The connectors themselves would change from time to time, which caused problems in molding, and sometimes caused the electrical performance to degrade. Getting parts to reliably meet a specification from China can be a problem. I can't even imagine the issues that could arise when you try to source an assembly, or completed product. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
