New CaptiFi Gen 3, High Power WiFi Antenna – With new WiJacker v2, USB WiFi Repeater

RadioLabs new and improved CaptiFi Gen II, the highest power, speed and output available. Our latest 3rd Generation Antenna system, connects at B/G/N speeds, in a fully weatherproof, purpose built WiFi Antenna system. RadioLabs is the only manufacturer, who incorporates a 100% weatherproof, fully encapsulated design, incorporating the most sensitive, high power USB Module into a rugged, well tested design. Our antenna provides up to 150 MBPS wireless throughput, and our USB Repeater, rebroadcasts this signal at a blazing fast 300MBPS networking speed. This is much faster wireless speed capabilities than the RV parks or Marinas even allow their guests to connect at. However, in the last few years the demand for streaming video, larger websites, FAST gaming and all internet activities has increased. The RV parks and Marinas have all provided more bandwidth to their customers. RadioLabs had realized this huge demand for bandwidth a couple of years ago, and in response, we fully redesigned the CaptiFi, 3rd generation antenna, as well as our WiFi USB Repeater system to give our customers huge bandwidth never before seen in the industry.

RadioLabs is proud to introduce the simplest kit available to repeat any WiFi signal, turning a public hotspot into your own private wireless network. Sets up in minutes. There’s simply nothing like it on the market. We see time and again, our competition using off the shelf items, throwing it together with a mass of cables, wires, home-built brackets and oddball antennas, taking low cost consumer based items, and trying to sell it as a kit. RadioLabs has never done this. We have very high quality machining here and we purpose build every antenna for one specific purpose.. keeping our customers connected while traveling, without having to worry about water leaks, destruction from the sun, cheap cables that aren’t UV grade and a system designed and built so well, that our WiFi Circuitry, cables and CNC machined hardware lasts longer than most customer’s own their RV or Boat. Customers call us all the time, who bought their RV second hand, and they’re using our antenna and repeater. We hear all the time that our antennas and repeater systems still look like brand new! Nothing makes us happier as a company than to hear our antennas are used by customers for well over a decade and it’s still performing like new! 

WiFi – Designed for RV and Marine applications – Rugged, Waterproof and FAST!

RadioLabs has been in this industry since 2002. We were literally the first company to develop a specifically designed WiFi system for RVs. Just a year later, we made a significant design change, and decided the Marine industry was just as important as our RV customers. At that point, we went to the drawing board, and developed a completely weatherproof antenna, that allows for the fastest connection speeds, but our antennas needed to not only have a strong signal, but also needed to be designed to handle full time outdoor weather, salt water, thrashing around on the deck of a sailboat 1000 miles offshore. We know the demands of our customers and designed all of our travel antennas, to not only provide a powerful, long range WiFi connection to the RV park or Marina, but also be brutalized outdoors for years. We custom design, machine and build all of our antennas in the United States and this allows us to control every aspect of our Quality control. Even the anodizing we use on our antennas, is designed to last decades, keeping the quality machined aluminum in excellent shape for years, even in the harsh salt water environment. 

Interested in trying our best selling USB WiFi Router Repeater, but don’t know where to start? Well now, RadioLabs has brought our two premiere products together into one kit. The CaptiFi USB Antenna has proven to be the most reliable and compact marine antenna, and pairing it with our USB WiFi Router Repeater allows anyone to set up their own personal hotspot.
Works on ALL operating systems, even cell phones, tablets.. anything WiFi enabled!

4 simple steps to surf the web seamlessly on your own independent WiFi Network:

  1. Plug in the CaptiFi antenna to the USB Repeater.
  2. Locate and Capture the desired public or private WiFi signal.
  3. Name SSID of your own personal Access Point ex: “Bobs House”
  4. Surf the web on your own 100% independent network!

The USB Router Repeater works by bringing in distant wireless signals through a USB antenna, then re-broadcasting those signals so local devices can connect. This allows phones, tablets, laptops, and virtually any other WiFi enabled device to receive a strong and consistent signal without having to each have their own powerful antenna.

The CaptiFi USB Antenna has stood the test of time and strength by being one of our most reliable weatherproof antennas. It can stand up to frozen rain, broiling sun, high winds and still be a highly reliable long distance wireless solution. At distances of up to 1 mile, the CaptiFi outperforms most any standard consumer wireless card.

The CaptiFi uses a 1 inch standard threaded marine base, making it simple to attach to any boat or RV. The 15 foot attached cable then plugs directly into the USB Router Repeater and with simple set up through the installed firmware, repeat any signal as your own personal, private WiFi gateway.

There are no software or drivers required to setup and use the USB Router Repeater, just a computer with a standard web browser installed. The Easy Setup configuration tool connects the USB Router Repeater to an access point, then allows you to set security and a personalized name for your hotspot.
