[time-nuts] Teardown of Chinese made eBay GPS antenna.

I can confirm that they work well on Glonass and Beidou. I have not tried them on my Z12 with L2 signals. Last night a big lightning strike across the street took out a tree. Antenna survived without damage, but my antenna is on a 3 foot tripod on the ground... it was quite a

Re: [time-nuts] Teardown of Chinese made eBay GPS antenna.

Hi So, after only two months in transit my examples of the “Chinese GPS Antenna” are here to poke at. They are from www.stotoncn.com and are labeled as being their part number GN-GGB0710. They clearly show 3.3V to 18V as the operating voltage on the box they came in

With respect, Tom, discussion of quality issues is scarcely "social media." But...it is your list so that's the last you'll hear from me on the topic. On Thursday, February 22, 2018, Tom Van Baak wrote: > Let's keep this thread on topic and highly informative. > > Please

Fine. The Chinese have no concept of, or ignore, intellectual property rights. They will cheerfully use 13 year old girls to put together stuff using counterfeit parts and ripped circuits. There is little or no quality control. The problem is that these goods drive better goods out of the

Re: [time-nuts] Teardown of Chinese made eBay GPS antenna.

Hi As mentioned in another post, the part does claim to have thermal limit built in. They appear to pulse test them at 150 ma and 16V so there is indeed *something* that would suggest operation at 12V would be ok. I’d guess that the thermal regulation spec applies up to 16V and past that you are

For those who have been following the saga of the Chinese made, eBay purchased antenna that failed, I may have an answer as to why it failed. I had to destructively disassemble it. I just could not get it apart any other way. I used a Chinese version of a Dremel tool with a metal saw blade. After
