How to build a tin can waveguide antenna

How to build a tin can waveguide antenna
Assemble the probe and mount in can Now you'll need that bit of wire. You'll need a soldering iron or a friend with one as well. Cut the wire so that when it is stuck in the connector as shown, the total length of both the brass tube and wire sticking out past the connector is 1.21". Get as close to this length as you can. When you've got your wire correctly sized, solder it into the connector keeping it as straight and upright as you can. Connect your antenna to your wireless card or access point To use your cantenna, you'll need a special cable commonly called a "Pig Tail". You'll want to have a wireless NIC or access point with an external antenna connector. Hook up your cable, point the antenna at a friend's, and see how far you can stretch you network. This antenna has linear polarization. For more information, check out these resources: Go to the Homebrew WiFi Antenna Shootout Go to the Wireless Home Related:  Amateur Radio VII

130 foot doublet / open wire line In simple terms, true open wire line (sometimes called tuned feeders) has lower loss for two reasons: 1. The range of average impedances it operates at is generally much higher, with more voltage and less current. The reduced current lessens the ohmic losses in the skin-effect surface of the conductors. This tradeoff places more stress on the insulating materials, which must withstand more voltage without arc-over and must not have much leakage resistance between conductors. 2. For you diehards who really prefer coaxial cable, and want to use a tuner in the shack to solve high VSWR, there is a low-loss solution: Click here to see the high performace coax. From Terman, Radio Engineering, 2nd ed. p 700: "The losses in a properly constructed line can be made very small. He continues: "A two wire transmission line radiates very little energy because the close proximity of the two conductors carrying current in opposite directions very nearly cancels the radiated field.

Mike Rutzen's Shark Diving Unlimited Why Your Wi-Fi is Slow (And How You Can Fix It) May 09, 2012, 4:44 PM — The first 801.11ac chipsets are coming soon, but 802.11n is likely to stick around for many years to come -- both in the business world and our homes. Unfortunately, the 300Mbps (megabits per second) that the n-standard promises rarely delivers anything even close and proves to be a massive bottleneck in the days of 50/100Mbps (or more?) broadband connections, 1080p video streaming, massive backups and so forth. On the business side of things, even menial tasks such as remote desktop or real-time collaboration suffer from a poor Wi-Fi-connection. [ 8 free Wi-Fi security tools ] In some of our tests, it wasn't uncommon that a 802.11n connection with devices only a few meters apart (and with only wall in between) can fall back to a mere 2-15 Mbps. If you're sick of slow Wi-Fi speeds but hate to go back to Ethernet, we've got a handful of tips that'll help boost weak signals. 1. Some routers are set up with their "Power savings" mode on by default. 2. 3.
