  1. SMA connector design

    DavidER replied to sandeepv's topic in Modeling antennas

    But if the distance between the reflector and the antenna disk is smaller, and the length of the central core of the connector is longer, then does the core need to be shortened? Is it possible?

  2. Bester Antenna

    DavidER replied to Admin's topic in Antennas for 2.4 GHz band

  3. If you place two antennas in parallel and connect 2 ports independently, will they work well?

  4. Bester Antenna

    DavidER replied to Admin's topic in Antennas for 2.4 GHz band

    Suitable for modem router zte mf920vs?
  5. Does this antenna operate in the frequency range 1800-2100? Because when I tested the antenna, it picked up frequencies 1800 and 2100.

  6. Bester Antenna

    DavidER replied to Admin's topic in Antennas for 2.4 GHz band

    What do you mean, more signal? Show with an example.

  7. Bester Antenna

    DavidER replied to Admin's topic in Antennas for 2.4 GHz band

    Is the distance 164mm between the reflectors?

    What is the cup for? What does it give?

  9. Bester Antenna

    DavidER replied to Admin's topic in Antennas for 2.4 GHz band

    Are there lids of this size?

  10. Bester Antenna

    DavidER replied to Admin's topic in Antennas for 2.4 GHz band

    solid lids? Shouldn't they be cut?
  11. And how to arrange 2 ports? 90 or 120 degrees?
  12. Yes.
  13. Will it work on 2 ports with a 75 ohm cable?

  14. WiFi/LTE antenna BDM-2

    DavidER replied to Admin's topic in Antennas for mobile communications

    Will it work on 2 ports with a 75 ohm cable?
  15. I watched. How many disks can you add to an antenna? Until 12, 16, 20?
  16. Then why not 50 ohms?
  17. You claim that the cable is 75 ohm for a TV. How can I explain what is used for the 1800 antenna?

    Which 2400 antenna with 75 ohm cable is suitable for a modem? https://jekolo.com/jekolo1/product/zte-universal-portable-4g-lte-wifi-mifi-modem-mf920vs/
  20. Does it work with a 75 ohm cable?
  21. And at what distance should they be placed?
  22. Is it possible to use 2 cables for the antenna?
  23. Does this antenna work with a 75 ohm cable?
  24. How many kilometers does such an antenna take?
  25. Are these dimensions correct for a 75 ohm cable? I have such an antenna did not work.
