  1. Closed: Re: Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    Thank you E.Kafeman and Volker and everybody,

    I will keep your recommendations and advice in mind.

  2. Closed: Re: Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    Thank you for your careful and detailed reply E. Kafeman. I will give the points you made in your reply much consideration. Can you recommend a reliable and inexpensive diode detector and VSWR meter?...

    Brian (and FvM),

    Thanks for your replies. Regarding boom width, I took that into account. The VK5DJ calculator allows the designer to enter a boom width. I think I used about 26mm for a width. I...
  4. Closed: Re: Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    Thank you FvM,

    It appears, however, that you (and Volker) believe that I am still trying to build the 20 element Yagi antenna described in my first posts. I am, however, attempting to build a...
  5. Closed: Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    Hello,

    Can anybody tell me the advantages and disadvantages of using a simple dipole compared to a folded dipole as the driven element in a 2.4 GHz (wifi) Yagi antenna?

    Is there, for example,...
  6. Closed: Re: Recommendation needed for gain of antenna for a 2.4 GHz wifi extender

    Thanks vfone,

    I will think about a cantenna instead of a Yagi. My wireless extender has a female RP- SMA input (wikipedia link) for each detachable antenna, it looks like the N connector in the...
  7. Closed: Re: Recommendation needed for gain of antenna for a 2.4 GHz wifi extender

    Thanks vfone,

    Does this antenna have advantages over a Yagi?

    In terms of gain?

    In terms of size?

    In terms of ease of building?
  8. Closed: Re: Recommendation needed for gain of antenna for a 2.4 GHz wifi extender

    Thanks for your reply Brian. The only real structures between the signal source building and the Netgear extender antenna I am presently using are glass windows: a house kitchen window in which the...
  9. Closed: Recommendation needed for gain of antenna for a 2.4 GHz wifi extender

    I need some recommendations regarding the kind of performance I can expect from various gains of omnidirectional wifi antennas that could be attached to a wifi extender (the extender has detachable...
  10. Closed: Re: Why does my homemade Yagi wifi antenna perform so poorly?

    Thanks Big Boss, I will consider that type of connection.

    I have concluded that I am going to reconsider my situation at this point. And I am going to slow down & try...
  11. Closed: Re: Why does my homemade Yagi wifi antenna perform so poorly?

    Just in the way of a little more explanation about educated guesses with respect to the 3 commenters, I have attached pictures from the posts of commenters myjunkmailbox2013 and zwzserver at ...
  12. Closed: Re: Why does my homemade Yagi wifi antenna perform so poorly?

    volker,

    I appreciate the replies you and others have made. I actually have a degree in physics and EE, but I never studied antenna theory and it has been years since I have thought about...
  13. Closed: Re: Why does my homemade Yagi wifi antenna perform so poorly?

    Thanks Volker, It may be that the need for a balun depends on the design given that I was following.



    OK thanks Volker, I will take that into account.



    Ok I will think about this. I...
  14. Closed: Re: Why does my homemade Yagi wifi antenna perform so poorly?

    The page at this link http://vk5ajl.com/projects/baluns.php#voltage seems to say that you can use a different cable to make a balun than the cable used to connect to the driven element: "It is...
  15. Closed: Re: Why does my homemade Yagi wifi antenna perform so poorly?

    Thank you FvM,

    What kind of cable should I use to make the balun at the link you gave? The same coax cable I am already using? Do you think it will make a major difference in performance?
    ...
  16. Closed: Re: Why does my homemade Yagi wifi antenna perform so poorly?

    Thanks FvM,

    Do you have any suggestions for how to improve my situation? Can I make a balun or buy a balun? Can I improve the coax connection in some way?

    The present coax connection is a...
  17. Closed: Re: Why does my homemade Yagi wifi antenna perform so poorly?

    Volker,

    Thanks for your reply. How precise do you think one has to be? In the online design at the link I gave, the designer said to within 0.5 mm was sufficient. I tried to do that as much as I...
  18. Closed: Re: Why does my homemade Yagi wifi antenna perform so poorly?

    Thanks for your reply FvM, The pictures are somewhat misleading, because the white foam board is opaque. Element #2 actually goes through two holes in the foam board and "folds" around the foam board...

  20. Closed: Why does my homemade Yagi wifi antenna perform so poorly?

    Hello everybody,

    Can somebody tell me why my home made 20 element Yagi directional antenna does not seem to have much “gain?” It does not seem to increase the range of the wifi extender (Amped...
