And this patch antenna with a parasitic director placed in a conical reflector...

Antenna is made from a box of coffee Amigo...

4 dipoles Lazy H panel antenna placed vertically ...

2x2 antenna panel of caps coffee cans...

For my first post I will begin with animated images previously posted on other forums ... !!! I hope you enjoy...!!!

Another antenna geometry...which can provide a greater bandwidth....!!!

Great achievement by sgser-user ...on 3G(1850-2200MHz)

By activating this feature you can deny access to your access point via Wi-fi network, but it will not protect you against sniffing or intrusion into your network. Remember that wrong hardware configuration that supports even the most modern security technology, will not provide the proper level of security to your network. Each standard has additional technologies and settings to maximize security. We therefore recommend to entrust the setup of Wi-Fi equipment only to professionals.

Free Wi-Fi While commercial services are trying to use existing business models to wifi, many groups, communities, cities, and individuals to build free Wi-Fi network, often using a common peering agreement in order that networks can freely communicate with each other. Free wireless networks are usually represented the future of the Internet. Many municipalities together with local communities to expand free Wi-Fi network. Some groups are building their own Wi-Fi network based entirely on voluntary help and donations. For more information, see joint wireless & networks, where you can also find a list of available Wi-Fi networks located around the world (see also Free Wi-Fi access in Moscow). OLSR is one of the protocols used for the creation of free networks. Some networks use static routing, while others rely completely on OSPF. In Wireless Leiden developed their own software for routing called LVrouteD to combine Wi-Fi networks, is built on a fully wireless basis. Bo?most networks based on open source software, or publish the scheme under an open license. Some smaller countries and municipalities already provide free access to Wi-Fi hotspots and Internet access via Wi-Fi at the place of residence for all. For example, the Kingdom of Tonga or Estonia, which have a large number of free wifi hotspots throughout the country. In Paris, OzoneParis offers free Internet access is unlimited to everyone who contributes to the development of Pervasive Network, providing the roof of his house for the installation of Wi-Fi network. Unwire Jerusalem is a project of the installation of free access points Wi-Fi in the major shopping centers of Jerusalem. Many universities provide free access to the Internet via Wi-Fi for its students, visitors and all who are on campus. Some commercial entities such as Panera Bread, offer free access to Wi-Fi for regular customers. McDonald's Corporation also provide access to Wi-Fi under the brand 'McInternet'. This service was launched at the restaurant in oak brook, Illinois; it is also available in many restaurants in London. However, there is a third subcategory of networks communities and organizations, such as universities, where free access is granted to members of the community, and those who had not included, access is granted on a paid basis. An example of such a service — Sparknet in Finland. Sparknet also supports OpenSparknet project, in which people can make their own access point part of Sparknet, gain some benefit. Recently commercial Wi-Fi providers have built free Wi-Fi hotspots and hotzone. They believe that free Wi-Fi will attract new customers and investment returns. The Advantages Of Wi-Fi • Allows you to deploy a network without laying cable, can reduce the cost of deployment and network expansion. Places where you cannot lay cable, for example, outdoors and in buildings of historical value, may be served by wireless networks. • Wi-Fi devices are widely available on the market. And devices from different manufacturers can interoperate at a basic level of services. • Wi-Fi networks support roaming, so the client station can move in space, moving from one access point to another. • Wi-Fi is a set of global standards. Unlike cell phones, Wi-Fi equipment can work in different countries around the world. Disadvantages Of Wi-Fi •Frequency range and operational constraints vary across countries; in many European countries, you are allowed two additional channels, which are banned in the US; Japan has one more channel in the upper part of the range, and other countries like Spain, prohibit use of low-frequency channels. Moreover, some countries, such as Italy, require the registration of all Wi-Fi networks operating out of the premises, or require registration of the Wi-Fi operator. • Quite high compared to other standards the energy consumption that reduces battery life and increases the temperature of the device. • The most popular encryption standard, Wired Equivalent Privacy, or WEP, can be cracked relatively easily even with the correct configuration (because of the weak strength of the key). Despite the fact that the new devices support more advanced Protocol Wi-Fi Protected Access (WPA), many older access points don't support it and require replacement. The adoption of the 802.11 i standard (WPA2) in June 2004 makes available a more secure scheme, which is available in new equipment. Both schemes require stronger password than those typically assigned by the user. Many organizations use additional encryption (e.g. VPN) to protect from invasion. • Wi-Fi have limited range. A typical home Wi-Fi router with 802.11 b or 802.11 g has a range of 45 m indoors and 90 meters outdoors. Distance also depends on the frequency.Wi-Fi in the 2.4 GHz range is more than Wi-Fi in the 5 GHz band, and has a radius smaller than Wi-Fi and pre-Wi-Fi) at the frequency of 900 MHz. • Signal interference of a closed or using encryption access points and outdoor access points operating on the same or adjacent channels may interfere with access to an open access point. This problem may occur with a high density of access points, for example, in large apartment buildings where many residents put their access point Wi-Fi. • Incomplete compatibility between devices from different manufacturers or incomplete compliance may lead to limited connectivity or slow.

What can be done from a box of instant coffee...

Ok, and how to do it..??

Below, shows how the construction of these antennas...

Achievement practice...

2,1-2.6 GHz Broadband Panel Antenna 16 dBi is a high performance broadband panel antenna. The unique combination of high gain and wide bandwidth make this antenna useful for broadband or multi-band microwave receivers and transmitters.
