Driven by the latest NextG 820.11n High Speed USB Wi-Fi dongle with a built-in RF amplifier, this slim and handy USB-Yagi directional antenna delivers a remarkable horse power of 2200mW at a top speed of 300Mbps.

Unlike most Yagi antennae with long broom and numerous director elements, the design of the NextG USB-Yagi aims at reducing the overall length of the antenna and whilst exceeding the isotropic gain with a wide 56 deg HPBW (half power beam width) beaming aperture to pick up the Wi-Fi signal nearby and afar, blending the best of both worlds.

See the excellent antenna performance below.

It is also slim and light weight that you could carry it in a traveller bag.

From a technical standpoint, no antenna can be designed with purely trial and error, let alone the ones without calibration and tuning which turn out to make a hugh difference in performance.

We use computer aided design (CAD) to engineer the seamless integration of the BALUN (the antenna's driving element) and the USB dongle (radio), a critical differential advantage for matching the impedance in the light of maximizing the signal transmission and penetration without incurring power loss in coaxial cable.

The antenna is made of rigid metal frame and elements so that its geometry, particularly the driver loop element, stays intact against transportation or normal usage for peak performance

As a result, it instantly improves your computer's Wi-Fi reception capability beyond the built-in standard factory gears.

It works within minutes. Simpy plug in the USB2.0 cable of the NextG USB-Yagi antenna to the laptop or desktop PC followed by a few simple clicks for CD-ROM driver installation - There is absolutely no need to worry about the cable compatibility issue.

What's more? You could construct a High Power Universal Wi-Fi Repeater with the additional 11N USB-Omni AP/Repeater kit. Typical application is to pick up Wi-Fi signal from ashore and let other computers share the Internet simultaneously.

Here's how it works. Use the USB-Yagi to catch the remote signal and share it amongst the other Wi-Fi PC clients with the 11N USB-Omni AP/Repeater. It works with all brands of (remote) wireless router, including OPEN or secured WEP, WAP/WAP2 PSK AES TKIP and 802.1x RADIUS server such as BT Openzone and Free Wi-Fi. Detailed Universal Repeater setup manual is included in the 11N USB-Omni AP/Repeater kit.

Simply faster and more powerful!!

 

 

Solution of eliminating a long and high loss coaxial cable to install an antenna at a sweet spot for optimal signal reception

Signal attenuates in the presense of obstructions such as wall, trees, building and a concealed in-house WiFi hotspot without an external antenna. A sweet spot is a location where you have a direct line-of-sight towards the signal source. It makes a difference in signal reception if you are able to setup your antenna in a sweet spot with minimal obstructions.

Sometimes a sweet spot is near a far corner by a window or at an attic overseeing the remote Wi-Fi hotspot. You may also need to mount your antenna on a mast for best signal reception.

The problem would then be running a long RF coaxial cable with so much signal loss that completely offsets the signal gain at the sweet spot.

For instance, the signal loss of a 50ft cable RG-58 is 16.1dB at 2.4GHz. If the antenna gain is 18dB, it could be reduced to 18dB - 16.1dB or 1.9dB.

 

 

So the solution is to eliminate the RF coaxial cable by using the Catch n Share Repeater to work with the 2200mW NextG USB-Yagi TurboTenna, so that it extends digital signal over the Ethernet cable that could go as far as 1000ft without signal loss.

You could terminate the Ethernet cable on either a computer or the WAN port of a 802.11n or 802.11ac router that you could establish as your in-house hotspots for sharing the Internet with phone, touchpad, notebook, macbook. See above diagram for reference.

Some buyers reported that the signal strength was further increased by installing a wall mounting kit at an elevated level rather than setting up the antenna behind a window. The USB amp was removed from the Yagi and kept indoor with the use of the 6FT RF cable. Lightning arrestor is strongly recommended if the Yagi outdoor mounted outdoor.
