Homemade Omni-directional Wi-Fi antenna.

If we had to participate in field tests of a transceiving apparatus, part of which was various types of antennas, and as Omni-directional, they are independent from the design and the claimed gain in performance for range transmission and reception is insignificantly different from each other. A significant difference was their price. Of greater importance, as we understand it from practice, had such option antenna as it is  efficiency, which directly connected with the working surface (the larger antenna size than she is better), but not with the stated gain. So simple homemade omnidirectional antenna is not what is not inferior to similar fancy designs.

 For beginners, we don't would advise to grasp for the production of Omni-directional antennas with a large gain such as collinear or the like. Without skills and lack measuring instruments to achieve from these structures excellent results not will.
 The antenna that we propose to assemble, has an important property. First of all, it is quite simple and broadband (bandwidth 200 MHz), this means that miss relative to the fundamental frequency of transmission and reception as a result of the inaccuracy construction will be difficult, which is an important factor in the case the lack of measuring devices.       
 However, simple a homemade antenna will differ markedly from the purchase of the product may because a nested design energy of creativity yields results.
The antenna is a quarter-wave vibrator with a counterweight
