I thought it was not working. Maybe it have a low channel gps chip and can't watch for many satellites while downloading the GPS almanac/cold start for the first time.

      Sure, it won't be perfect but radios have protection and it's ok. You will loose power on transmit a bit.

      I know the sizes. But this is dualband antenna it's more complicated than just size. Because it resonates on 2 bands and it have some matching elements.

  • @bart2903
    @bart2903 5 лет назад

    did you test, or even do SWR tuning / cutting on the antenna? like to see what's the SWR, before, AND after tuning. it's normal that you first have to do SWR setting, for optimal working. I ordered last week these antennas to try out for myself: 2x Diamond SG-7900 158cm Nagoya NL-770R 96cm Nagoya NL770S 40cm (2019 model, new spiral) Nagoya NL770S 95cm (old version classic spiral) Nagoya NL-77H 43cm 60$ total cost! so cheap, it's worth to try ;) And a SureCom SW-102 (new upgraded version) digital SWR / Power meter. also for just 50$

    • @todop
      @todop 5 лет назад

      It was tested with antenna analyser. And I don't know how you tune these type of antennas. If you do you can send me a guide. And trimming won't help. It needs to be longer for the lower frequency

    • @bart2903
      @bart2903 5 лет назад

      first you need a SWR meter, and put it between de tranciever and antenna. be sure that you have no loss. I saw a box between you antenna and tranciever. go for the BEST wires, keep them short.. dont rol them. @@todop :) this guy does a simple video: ruclips.net/video/PEXKV_Mti60/видео.html another longer version, go's further in fysics of the singal and how it's generated en transfers in the air ruclips.net/video/jBItVeeynco/видео.html
