CaptiFi Marine or RV high power long range omni directional USB WiFi Antenna/adapter Range up to 1 km

The Simplest WiFi System just got smaller!

A complete wireless solution with nothing else to purchase! The wireless card is actually built into the antenna!

“All-in-One” wireless system with a simple connection over a computer's USB port. The CaptiFi Long Range Wifi Solution works with Windows, MAC OS X and Linux.

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.

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.

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. Typical results give up to 30 times the range of notebooks with integrated wireless. 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. (Marine Mount not included)

Note: The Drivers for the CaptiFi are compatible most operating systems including Windows 98SE/ME/2K/XP/Vista and 7. Also compatible with MAC OS 10.3 through 10.6

The CaptiFi is an extremely versatile antenna for long range connections. It's compact size and weatherproof design means it will fit almost anywhere. Easily portable, the threaded base allows easy removal and relocation with no clamps or bolts necessary. 
Antenna base is threaded to fit a standard 1" marine antenna mount. You can also use a simular mount or pipe for your yor RV.
