Grid antennas and Yagi's

I research new wifi technologies, and i bench test wireless RF amplifiers and misc.

I recently bought a couple of grid antennas and Yagi antennas, and low loss cable to test long range wireless networking and the maximum range that could be achieved using these highly directional wifi antennas.

First of all i would like to tell that wifi grid reflector antennas are not for normal wifi, they are highly directional, and have a very narrow beamwidth, which makes it highly unfeasible for a general purpose omnidirectional wifi usage.

If you want to estabilish a Point-2-Point long range wifi link, as in a BackHaul or others, then this is probably the best situation, i mean although you need to make sure that the path is LOS(Line os Sight), and that the fresnel Zone is not blocked, as in long range wireless networking, the Fresnel Zone effect is all the more significant.And you can also add a few amplifiers if you are getting a veyr weak signal at the other end, and your Free path loss is very high.Make sure though that you dont exceed the FCC 15.204 Legal limits.

The antennas i bought were a hyper link HG24 24Dbi grid antenna and a hyperlink 14.5 Dbi Radome enclosed Wifi Yagi.They far outperformed all those cheap antennas we get on ebay.Another good company for wifi antennas is Andrews which makes excellent wifi grid antennas.

Setting it up was not that difficult, the more difficult being configuring the parameters, to fine tune the sensitivity.

Also a Spectrum Analyzer or SWR power meter is extremely helpful as you dont want extra power to be transmitted, and stay well below the FCC legal limits, the Spectrum Analyzer will help you to Site survey the area and also will show the signal levels of the incoming RF wifi signal.
