Yagi Antenna 5 8GHz
Вставка
- Опубліковано 18 вер 2015
- In this video I will show you have to build a Yagi antenna for 5.8GHz. It is quite small but if you follow the methods I use you should have no problem building your own. The Yagi has just 5 parasitic elements but this ensures it has a wider beam angle although in having a wider beam doe’s sacrifice range. You can if you wish add more parasitic elements using the same measurements

A lot easier to make then the biquad yagi.
Another awesome video, thank you Andrew.
I eagerly await your longer Biquad Yagi kit.
Thx bro!!! I bought a bunch of high powered transmitters and antennas, but couldn`t get a good range. Then I build one of these. And even if my lady and friends were laughing about me, I gave it a try. I endet up at around 1.6km. But the best to come: I forgot to power up the transmitter via smart audio, so the range was claimed at 25mW!!!
Hi Andrew, for this design (1 λ driven element) you are actually building a quagi. The only difference that I see is that your back reflector is not a closed loop. Congrats for your videos you are doing a public service in public education!
a thought use a straight edge to line up the parasitic elements .. I very much like the details in the builds you add.using the benchtop to make sure the parts all line up, priceless
+craig palmer Cheers Craig
andrew ,
I watched some videos on youtube channel where used helical antenna pointing for metallic plate, like the principle of satellite dishes , so better dissipates the signal ? If I put a mini yagi antenna reflecting work? I use the 5.8 boscam the 5885 channel , what do you think ?
as you have shown before on the 2,4 the signal graphs, do we expect this to be as good. my router is both frequency bands
thank u ... i will make it
What is the best for distance on 5.8, if not a Yagi? A 4 element panel?
Hello Andrew, may I ask you which is the expected effect if I should add one more element ?
I'd like to see how that perform on a VRX for long/mid range FPV... I'm thinking to give it a try...
Awesome job and video! Please, make one about LTE! :)
Hi, only a question : Not using any Balun at all?
like the upside down table surface Alignment gj
Can you do a test on a 2.4Ghz Yagi as a Radio Transmitter?
Hi, Do you have any dual linear desing?
Hi Andrew. Can this be done on Perspex?
May I ask you if you think this type of antenna would be good for a transmitter? I'm seriously feed up with all the antennas that are sold that supposedly give your more range ... but it finish been a truck load of horse manure I did use. Custom, Tuned, Circular Polarized antennas "Really expensive ones.. until a day that I didn't have other choose but to test with a regular antenna to find out that the regular was at least 20 times more powerful than the ones that I was paying an arm and a leg....
Would you please consider to advice on a directional transmitting antenna? please??
yeah, unless you're flying in a straight line, a directional antenna has to be pointing at whatever it's transmitting/recievng from. you can probaly use a auto tracker, but that would add a lot of weight, and as long as you're using a omni on one and a yagi on the other, it's the same vice versa
Awesome video Andrew, could you make a 24gb and 60gb yagi, these are the other legal frequency and are often used by ubiquiti ants.
These would make very Interesting and entertaining videos
What type of wire did he say at 3:39?
Sir do we have to solder the closed loop with one end to core element and other to ground ie outside the core??
Yep, centre of coax to one side of the loop, and shield to the other. It makes a close to 50 ohm feed, give or take.
Thanks Andrew! off to the electronics supply shop to build this and the crosshair today.
+Hoverbot1TV No problem let us know how you get on.
can you pls build a 5.8ghz parabolic antenna?!
Andrew Are the elements steel or alumunium and do they have to be a fixed diameter? please forgive my naivity I'm a complete ameteur I only ask to see if weight can be saved.
+John Vickers Hi John they are steel but you could also use those cheap telescopic tv aerials break it down and use one of the tubes.
+andrew mcneil Cheers for answer.
I Andrew and thank you for all these videos.
I have a question for you; is there any concern using a 4 mm in diameter instead of 3?
And what about to use iron instead of aluminum?
you could use 4mm but iron is a poor conductor when compared to copper and aluminium
Thank you, I used 4mm aluminium ... just to be sure it will work “on the field”
Hi, can you add the calculations in the videos?
Black paint is wrong for 5.8GHz. Do you know that?
Hello, can one-way receiver antenna that can detect 100ghz em wave with 1ghz be designed?
or, how many ghz can be designed from 1ghz up?
Short answer no and the equipment to detect and analyse waves past 50 GHz would cost the same as an average house
@@andrewmcneil Thanks for answere.
Thanks for the video, but why would I want to use yagi instead of helical?
+Martin Brychta To be honest I think it is that some people like to experiment as I said in the video it has been requested many times.
The helical is a circular polarized antanna - wich is good to get rid of multipathing because it rejects inverted signals but it's range is not as high as the range of a linear polarized antenna like a yagi.
i did 3d print one
Wrong concept. Where is the balun trafo? Sufni tuning :D
