Dirt Cheap Bi-Directional Antenna Wirelessly Extends Your LAN

By Jason Fitzpatrick on November 28th, 2012

If you’re looking for an effective way to link remote LANs without the hassle of laying cable, this DIY bi-directional antenna is a quick (and cheap) method for bringing internet access to outbuildings and other locations.

Tinker Danilo Larizza needed to share internet access between apartments that are relatively close together but not hardwired–ruling out simply sharing the access via existing LAN infrastructure. His solution combines a simple scrap wire antenna array mounted inside a plastic food bin (seen here with the cover removed to show the antenna) and some coaxial cable to link the antenna to two routers.

Our favorite part about his build is that he constructed the pair to establish if the antenna setup would even work in his location and intended to buy commercial antennas if it did; his Tupperware models worked so well, however, they’re now the permanent solution. Hit up the link below for more information about the project.
