Lincomatic's Homebrew WiFi Antennas Lincomatic's Homebrew (DIY) WiFi Antennas One of my latest obsessions is building DIY homebrew WiFi antennas. Heinz Beans Cantenna This is the first antenna I built.

Mar 24, 2008 - The first antenna we'll look at is called a Cantenna. For an online calculator or you can run through the equations yourself. Build A Tin Can Waveguide WiFi Antenna http://www.turnpoint.net/wireless/cantennahowto.html. Waveguide antenna calculator. Which gets complicated, it seems that a waveguide antenna or 'can-tenna' should have parallel sides, be a good conductor,.

It's the ubiquitous circular waveguide 'cantenna': I obtained my can by going to my local 99 Cents Only store and buying a can of Heinz beans, which happened to be desired 3.25' diameter. The resultant methane gas produced from consuming the beans was used to power my soldering iron afterwards. I will not go into the construction details, as they are very well documented on. Finding his online cantenna calculator rather intriguing, I set out to find the mathematical roots to his calculations. The result is my own, which I wrote in in C++, based on formulae obtained from the Antenna Book. It's available on my; the archive contains both a Win32 console-mode EXE and full source code. In addition, Adam Lesser has kindly supplied a binary for OS-X.

Greg Rehm's calculator fixes the operating frequency at Channel 6 (2437MHz), which is the center channel in the USA, giving the best tradeoff if you want to build a general purpose antenna which works across Channels 1-11. On the other hand, my calculator lets you tune your antenna for maximum gain on a specific channel; this is handy if you want to use your antenna set up a permanent point to point link. Let's go through an example using my calculator.

The syntax of the program is cantenna diameter centerchannel where diameter is in mm.

Wireless 2.4 GHz Directional Antenna Calculator This requires the use of enabled and capable browsers. This calculator is designed to give experimentation data for construction and use of a wireless range extending antenna. Detailed experimentation guidelines are below the calculator. Enter the diameter of the can and click on Calculate.

This idea is not new and has many names such as shell cell, cantenna, bazooka antenna, canned antenna and tin can annie.

Vnc server no root apk android. We like to call it a recycled waveguide antenna. Whatever you call it, it is an interesting project that takes very little time and very little money. Total time should be under an hour and total cost under $10.00, even if you don't have an electronics junk box at home. While this has worked very well for me, there is a certain amount of risk to equipment any time you experiment. We assume no responsibility or liability.

In order to do this, you will need to gather a group of materials needed. Call it scavenging or preparation; it should not take long. For one recycled dish, you will need: 1. 1 - N-Type Female chassis mount connector. 1 - Copper 12 gauge wire about 2 inches long. Several small nuts and bolts or other mounting hardware for mounting the connector. The N type female chassis mount connector is typically used in radio applications. Ipartition serial 34 trailer.

Hams and electronics hobbyists may have one hiding in the junk box. Most came so that they mount by way of four small screw or nuts and bolts; some had other mounting brackets. We will mount this to the our recycled directional dish. One side is N-female for connecting the cable from your wireless equipment. The other side has a small brass stub for attaching the small piece of wire with solder. The can that worked best for me was 3.25 inches in diameter.
