RV and Marine WiFi Antenna - USB wireless

Plug it into your USB port, install the software one time, connect to the internet, and enjoy ultra long range wireless at a blazing fast 150 MBPS! It's that simple. The CaptiFi has been the best single antenna developed for travel, period.

RadioLabs, ever pushing the Wi-Fi envelope, has developed a simple solution to the never-ending WiFi range problem. This is especially prevalent in the marine and RV community and in response to demand for a small high power receiver, we have developed the CaptiFi, the ultimate one piece Wifi solution. This unit is designed to provide long range Wi-Fi with a completely weather-proof easy-to-use antenna with a smaller than ever physical footprint.

NOTE: The video above is 6 years old, and we are currently working hard in production of a large video series on RadioLabs antennas. When the video is viewed on computer, there are annotations where corrections for specifications have changed. The antenna is B/G/N, 150mbps, compatible with ALL USB 2.0 and 3.0 ports, and operates on all operating systems and RadioLabs amazing WiJacker, USB Travel repeater. With the CaptiFi and the WiJacker combination, you can connect to any public access point anywhere, and turn your entire RV into it's own local access point, that the entire famliy can connect to and provide wifi to all your devices! Look for our new video coming soon, and follow us on Facebook for instant updates!

Extremely simple to connect– The CaptiFi is virtually a plug-and-play setup. With no additional equipment needed, just mount the antenna, install the included software, and plug the USB connector into your PC. You will see the difference in range and reception immediately.

Using RadioLabs' Wireless USB Utility (available from the included software CD), you can actively view your signal strength percentage, link quality and with a single click, all other available networks in range. This user-friendly interface allows you to save the hotspots/access points you have connected to, making password protected connections easier than ever.

This mature design, is extremely rugged and weatherproof, powerful, FAST, easy to install. Just like fine wine, we have improved it with age. This tried and tested design, was originally adopted from a custom RadioLabs proprietary high power antenna element, was originally designed for US Military use, where an almost impossible high gain signal was desired in areas which no traditional antenna was capable of operating. We designed and produced the element alone, in large quantities. Once that project was finished, we had no other immediate use for this high power antenna, so, we put it inside the CaptiFi to let our customers enjoy this fabulous high gain antenna and simple high power module

The CaptiFi Long Range Wifi Solution makes high speed access not only extremely easy to get, but readily available from the comfort of your boat, recreational vehicle, trailer, car, anywhere you need a stable wireless signal. No external power is needed, as the CaptiFi Wifi Antenna is powered directly from the USB port!

At only 9 1/2 inches (241mm) tall, this antenna combines the power and range of antennas and wireless receivers twice the size into a compact one piece unit. The powerful wireless card in addition to our proprietary 8dB omni antenna gives the CaptiFi an amazing performance boost. This revolutionary antenna element, originally designed by RadioLabs for military applications, increases the performance of the CaptiFi antenna by 20% over antennas of similar size. With both the receiver and the antenna built into a sturdy weatherproof assembly with sealed cable connections and a heavy duty anodized aluminum electronic housing, the CaptiFi will provide long range wireless connectivity for years to come.

The CaptiFi Long Range Wifi Solution is proudly made in the USA. We keep production of these close to our location so that we can ensure they meet our strict quality standards.

Antenna comes with a 15 foot USB cable hardwired and weatherproofed.
