Here is great video that shows how to make a super long WiFi antenna from an old DirecTV dish. Using a recycled satellite dish to make a long range WiFi antenna will enable you to pick up wireless internet from up to several miles away, depending on the antenna at the other end on the router.
If you don’t want to fool around with converting a DirecTV satellite dish to a long range WiFi antenna you can buy off the shelf antennas that actually perform much better.
Below are the components that I used for a long range WiFi antenna setup that picked up an open wireless connection from almost sixty miles away, from the top of Guadalupe Peak in Texas. For that experiment I used a 24 dB gain directional antenna connected with a 10′ length of cable to an Engenius EUB-362 long range wireless adapter. With that set up on a tripod I connected to an RV park almost 60 miles away in the town of Van Horn along IH-10. The elevation of my antenna for this test was just about 8700 feet and the elevation of the receiving antenna was at 4000 feet above sea level. See article on my long range WiFi experiment here: Long Distance WiFi Antenna Test
Above a Grid Parabolic WiFi antenna. Cost: Around $60 Combine the Antenna Above With The High Power WiFi Adapter Below:
Cost of the Engenius EUB-362 is around $38
Next you will need a length of cable to connect the long range WiFi antenna to the high power wireless adapter.
Cost of the cable to connect the antenna to the adapter: Around $20
That’s it. With the three items above you have an even higher gain WiFi antenna that the WiFi antenna made from a DirecTV dish in the video above. It is a much more professional looking setup as well.
