 Solder the balun at the feed point, this process seems to be a lot more easier, cleaner and looks like it is strong enough. |
 The first element is soldered at the centre pin and at the copper tube (right side of the pic) the other element is soldered at the centre pin of the balun, the distance of the centre pin from the reflector is 30mm, after soldering the two elements there is a 10mm gap from the “U” shape to the reflector and there must be something to support it like a stud or something. |

 I use a plastic tube that I got from my daughter’s playroom (a plastic xylophone stick) cut them in 15mm size, drill a hole underneath and another hole at the side (the hole must be 10mm from the bottom) then make a slit enough for the wire to get through. |

Wow! very impressive.
I’ve build several antenna for wifi but have never found a design for a sector before.
I look forward to you long distance results.

Got the idea, I am building a sector antenna based on your design, but will be using a different radiating element.

Perhaps you should put a link to the original design ?

@foobar
what makes you think that the link you provided is the original design? are you aware that the 4NEC2 has a template for that particular design? are you also aware that i have the pdf documents the chap did mentioned? he clearly states how he did his and none of your so called “orginal design” has the same dimemsion he used, although it has the same design look. That doesn’t mean he copied it or got the idea from your so called “original” design.
incase you are not familiar with the things i mentioned, STFU.!
give the chap some credit.

Great.
Can we increase the gain by increasing the number of elements.

My first project was a radio telescope 10 years ago, now I would like to build something that is
VERY directional and can send and recieve to and from wifi devices with a range of over 2km
what type of antenna is required I would rather build the thing myself if possible
Please help

Did yoy see amos 9 sector antenna? http://www.qsl.net/yu1aw/vhf_ant.htm Ithink it is a good antenna, i have made one and it works better than pacific wireless SA24-90-17 antenna, and i did not make it with perfect reflector. If some one try to make one i have interesting solutions for easyer making, contact me one zoran.s@verat.net.

I am going to build it soon and let gives u the result
