Build biquad wifi antenna

You will need to do a search for larger bi-quads. I am in the process of building a single biquad out of a dish I plan to mount the Alfa inside of the dish and USB out it's lower end into the laptop. It stands on a modified tripod guitar stand. Though I expect that to be an overstatement, I still will be expecting to see most of the APs in my small city of k people so it should be pretty noisy.. I am also researching converting everything including my Alfa over to type F connections for universality.

I understand that 50 ohm is the RF standard so I figure 50 OHM connectors and a very short length of series coax cable will do the trick.

I will report my findings in a few weeks. I'd very much like to read your findings so make sure you post a link. I think all the long distance connections are set up rather than random finds. In other words the claimer is optimising both ends; maybe a high-power AP possibly with a dish at that end too and then searching only for that AP.

I can get about 40 APs, in my street alone, with my current setup. Time to cast the net wider. The minimum range I will accept is roughly about yards, but of course I'd like a few miles of range. Your suggestion makes perfect sense regarding both ends being dish equipped. I'd bet that the AP had a unidirectional amplified feed as well, and possibly from a higher elevation to a lower on a fair weathered day. By TheGoodLife Follow. More by the author:.

You can apply varnish over copper cable to prevent corrosion. You can see my old antenna now began to corrode. TV antenna casing used to attach to Aluminium bar. In antenna setting of tour router setup you can see if your antenna working correctly or not. Choose auto mode. If antenna working properly Antenna 1 turns into External.

It can varely reach to 1mbps. It can easily reach 15mbps as you can see. But using RG cables are always recommended. If you have any questions or suggestions please leave them below.

A dish that big is usually overkill for most people and modern mini-dishes work just as well. The dish helps focus the radio waves onto a directional antenna feed. We're building a biquad antenna feed because it offers very good performance and is pretty forgiving when it comes to assembly errors.

Follow along as we assemble the feed, attach it to a DirecTV dish and test out its performance. With just a handful of cheap parts, a salvaged DirecTV dish and a little soldering, we were able to detect access points from over 8 miles away. Using consumer WiFi gear we picked up over 18 APs in an area with only 1 house per square mile. Biquad antennas can be built from common materials, which is nice because you don't have to scrounge around for the perfectly-sized soup can.

We did have to buy some specialized parts before getting started though. The most important part here is the small silver panel mount N-connector in the center of the picture; the entire antenna will be built on this.

We purchased it from S. Electronics, p art N The "N-connector" is standard across the majority of commercial antennas and you can connect them to your wireless devices using "pigtails.

We also purchased 10 feet of WBC coax cable so we wouldn't have to sit with the dish in our lap. We got our surplus DirecTV dish from F reecycle. We'll cover the reason for the mini butane torch later. Trevor Marshall built one of the first biquad WiFi antennas found on the internet. We followed the slightly more thorough instructions found at martybugs.

Here are the raw materials we started with:. The wire is standard solid-core 3-conductor wire used for most house wiring.
