    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? AmateurDIYAntenna

    Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    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 have attached the VK5DJ design parameters of the design I am using to this post. The width of the...

    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 different Yagi antenna that has only has 10 elements (8 directors), using this VK5DJ online calculator...

    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, a difference in gain? I am presently constructing such an antenna from 12 gauge copper wire (using...

    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 homemade Cantenna post above at **broken link removed** may fit a pigtail that is RG58 cable. If it...

    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? I have seen some people essentially combining both concepts: placing a Yagi with fewer elements in a parabolic reflector to increase range & gain. A.

    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 extender is mounted and a porch window in a glassed in porch. The signal source building is...

    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 antennas). I want to use the extender to supply wifi to a building by picking up a 2.4 GHz wifi...

    Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    Re: Why does my homemade Yagi wifi antenna perform so poorly? Thanks Big Boss, I will consider that type of connection. - - - Updated - - - I have concluded that I am going to reconsider my situation at this point. And I am going to slow down & try completing this Yagi later. But, I have a...

    Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    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 impedances, reactance, inductance, etc. I...

    Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    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 looked at my connection and the connection of...

    Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    Re: Why does my homemade Yagi wifi antenna perform so poorly? The page at this link https://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 important use the best coax you can...

    Simple dipole compared to a folded dipole in a 2.4 GHz Wifi Yagi Antenna

    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? Regarding the asymmetry of the coax...
