A cantenna will be easiest to dial in to a specific location. They are more directional, but will provide a great signal if you aim it at the distant router. A biquad would work also.
You don't have to use blank PCB for the reflector. You can use any material that's electrically conductive and will reflect waves (ie, any metal plate will do fine).
Hey buddy im thinking about making one of these to work with a dish. Where is a good place to get the cable to run to the antenna? I read it needs to be a certain type
I ordered my cable online with a male N to an SMA connector, the cable itself is an LMR-400. The thick cable helps retain much of the signal, the only thing on my mind is whether or not to shield the walls of the enclosure since it will be weatherproofed? I don't know if that would make it more efficient or less?
Yes, but it will only boost the 2.4 Ghz band. If your router has a separate antenna for the 5Ghz band then it will not interfere. If your router uses combined 2.4ghz/5ghz antenna then it will cause issues.
I have built-in pci wi-fi card, and the wifi router is about 500m away from my house, so which antenna i need to use, please help ! i'll build that antenna
Well, since it has no external antenna ports you would need to take the case off and solder the antenna on or buy an antenna mod kit from ebay or a modder website.
No you can't because of resistance and you well get less mb/s speed...the best thickness is between 2mm and 1.2 mm....the more thickness the more wide band of channels and more interference between them
@PedroSilvaStudios Just search for engadget and biquad. Also, martybugs biquad will bring up the guy that popularized it, however this design is constructed more like the engadget version. You can also buy them on eBay if someone gets tired of theirs.
hello, I am thinking of building one of the bi-quads to use with a dish I have. that would be connected to a alfa 1000mw Wi-Fi card. would this work ok with the dish if adjusted properly for the quad to the dish. thank you
sir i watch yr video i want to know regarding biqad antena. if i will use mobile charger power supply for biqad antena for boost wifi signal for my mobile its will work if no then how many valt give to biqad antena n its work or not
I made my biquad to fit to a BNC connector, then bought a bnc to rp-tnc male jumper to fit onto my wrt54g. I bought a 50' BNC CCTV cable but I'm getting no results when doing a site survey on the router....am I using too long of a cable? Any other suggestions?
Cable length shouldn't matter if it is good quality cable. Try it with a different shorter cable if you can to eliminate the possibility of a bad cable, also make sure all your connections are firm.
Like yer cable video stated... RG-59(coax) has a freq range up to 1GHz. Found a 3' RG-142 for $15 on ebay... Gonna try that out. Thanks for the response!
I know you posted your question a while ago, but there are two factors degrading your performance. regular Cable tv (or satalite dish) wiring doesn't have the proper impedance. you have to have a rating of 75 (not 50 as your example), so as not to lose too much signal per meter/foot. that is the majority of your signal loss, but also BNC connectors are notorious for being unfit for this frequency range (2.4, 5GHZ) Aaron, I've used a similar setup as yours for a site-2-site connection, and recommend using tomato firmware, if you aren't specialized enough to customize you're needs with openwrt. I'd also look into a more recent access point, as the WRT has been superseded by newer hardware. currently, I prefer some asus models.
You can see my other video for more cable info. It is youtube video v=AoquwWmVWOQ You can just put that in the search and it will come up. I used LMR400 cable which is coax cable that is tuned and shielded for antennas. Regular TV coax, like RG6 has high signal loss for wifi antenna usage and it not ideal. I got mine on eBay with an N connector for the biquad and an RP-SMA connector on the other end so it fits a standard PCI card antenna connecter. Hope this helps.
You STILL did not provide answer to the question-yes, a USB wi-fi adapter that USES an external antenna is needed. He can take apart the antenna that usually comes an adapter-it will have small dia. SMA cable inside of it. Remove the small diameter cable / wire from the inside of the plastic antenna housing. The exposed cable has small dia. wire inside of the braided copper sheathing-this is the signal wire - the sheathing is the ground wire. He needs to solder the signal wire to the bi-quad antenna and then connect the sheathing wire to the reflector plate that's directly mounted 15 - 16 mm behind the bi-quad. The bi-quad will need some sort of mechanical support as the tiny signal wire will not be able to hold weight of bi-quad. The cable should still have the SMA connector on other end - attach it to the wi-fi adapter and your done.
I wish you guys would STOP using panel mount N connectors in your projects, no wifi equipment uses them, you can't scavenge them from anywhere and nobody has them. I followed the math and built a cantenna today and it doesn't work worth shit even thought I used all the right diameters and lengths and checked my connections with a continuity meter... so I'm going to try and build a doulble biquad next. I'm probably going to use galvanized tin for my reflector and copper wire for my antenna.
This is a great video on the biquad. I think I've seen enough....that I can build one. The part I can find no information on is......how to connect to the router....and the pc. Is this really as easy as.....run the chord from the antenna in to the back of my wireless router .....and bam ? I just don't want to get too far along and then realize I have no idea how to connect to the router. Thanks

Nice job fella. Look forward to more great videos from you SIr.

You don't have to use blank PCB for the reflector. You can use any material that's electrically conductive and will reflect waves (ie, any metal plate will do fine).
That's a nice antenna. Do you have the link for the schematics?
Hey buddy im thinking about making one of these to work with a dish. Where is a good place to get the cable to run to the antenna? I read it needs to be a certain type
Will the biquad antenna work on a dual band router (dlink 825, 2.4 / 5 GHz) for both bands?
Actually, I agree. N mounts are hard to find and cost more than other types. They are only good if you already have antenna cables with N connectors.
I ordered my cable online with a male N to an SMA connector, the cable itself is an LMR-400. The thick cable helps retain much of the signal, the only thing on my mind is whether or not to shield the walls of the enclosure since it will be weatherproofed? I don't know if that would make it more efficient or less?
Can I arrange 4 of these back to back and attach them to a 4 antenna router to get an omnidirectional setup?
hi do you know why a 2.4ghz rubber duck antenna has a wavelength of 26mm when it should be 31.25?
Yes, but it will only boost the 2.4 Ghz band. If your router has a separate antenna for the 5Ghz band then it will not interfere. If your router uses combined 2.4ghz/5ghz antenna then it will cause issues.
I have built-in pci wi-fi card, and the wifi router is about 500m away from my house, so which antenna i need to use,
please help ! i'll build that antenna
Well, since it has no external antenna ports you would need to take the case off and solder the antenna on or buy an antenna mod kit from ebay or a modder website.
is thickness of coper element matter? example instead of 1.5mm can I use 0.5mm which is the coper I get from CAT 5 UTP?
No you can't because of resistance and you well get less mb/s speed...the best thickness is between 2mm and 1.2 mm....the more thickness the more wide band of channels and more interference between them

I have charter spectrum in a 1930s house with old wiring. The signal is in and out, not steady! Will this boost the signal and make it more steady?
Also, is this compatible with a Spectrum router?

Does the reflector plate need to be Copper or can I flatten out a thin sheet of Aluminum? I'm going to be mounting it on a satellite. .
Any conductive metal will work, but copper PCB is best
Thanks!
were do u buy the copper pcb and is there a special size i need
i have an alfa awus30h can someone tell me were to buy all materials needed and help me build this please help

how to connect antenna to laptop?
you need an USB wifi adapter with an external antenna

Dumb question----do these give you internet from cell towers or satellites ??

Yes! (Tested with a 3G bisquad antenna in a countryside with a 4G modem (no MIMO))

Sorry, I do not know why that would be.
