Significantly Boost Your Wifi Signal!

Indoor / Outdoor (IP65 Rated)

This is one of the best home, mobile, or RV WiFi Antennas made. The Super USB WiFi Antenna 3 plugs into your computer for powerful reception; no internal WiFi required! Installation is a snap and performance is outstanding. While testing it in our small town of Fortuna, California we were able to see an additional 20 wireless networks. On average, users can get 300 to 400 feet even through several walls. In further tests we were able to connect to a small wireless router from over 100 yards away, keeping 80% signal strength through several walls and obstructions. In one of our tests we even connected to a network a mile away.You may be surprised at what the Super USB WiFi Antenna 3 can do for you.

The antenna incorporates a water resistant design for outdoor use (IP65 Rated), along with wireless "N" technology for lightning fast file transfers with your "N" router. It comes with a 15-foot USB split cable that offers two plugs to your computer, although normally one plug is sufficient for powerful reception. The antenna mounts easily to a window with suction cups or to the wall using the lanyard and "hook and loop" mounting strip. If you are trying to receive a very distant signal from outdoors, then the best place for mounting the antenna is above the peak of your roof so that signals can be received from miles in every direction. A cable tie is included for pole mounting outdoors. You can purchase an additional 30-foot USB cable so that you can mount the Super USB WiFi antenna on a roof, a mast or in a window.

Compatible with 802.11 B, G, and N. Up to 150 Mbps. WEP, WPA, WPA2, WPS encryption compatible. Easy software included. Works with Microsoft Windows - XP, Vista, Vista x64, Windows 7, Windows 7 x64, Windows 8, Windows 8 x64, MAC OS 10.4-10.8. We are sorry but the Super USB WiFi Antenna 3 does not work on MAC OS 10.9.

The Super USB WiFi Antenna 3 is also compatible with Linux Kernel 2.6 and Ubuntu 10.10 — Linux/Ubuntu support not offered by C.Crane.

Weight: 1.8 oz. Size: 1.4" W x 10" L x 0.6" D.

Note: The Super USB WiFi Antenna 3 requires installation of software drivers. Gaming stations such as the Xbox® and the Sony PlayStation®, the iPad®, iPhone® and Android® devices are not capable of installing these software drivers.

Overall it is ok but in my opinion not as good as advertised. I have an ALFA card that was $40 and has almost the same strength as this Super USB WiFi antenna. I was expecting a little more but oh well, its an ok product. Can't wait for the next one to come out!

This WiFi Antenna is hands down the best. It allows me to connect to a business almost a half mile away. I do recommend buying the 30 foot cable for an extra 20 bucks. Two months time and this baby paid for itself. I am a very happy with my purchase.

This is a fantastic Antenna. My only wish is that there was a way to re-broadcast the WiFi signal so that multiple computers could share the signal. I do it now through ICS but it would be so nice to get the signal into the house where 3 PC's could share it. (idea?) Thanks for a great product. I used to get about 2 bars but now get 4-5 unless the link is being saturated by streaming kiddies (the 2013 baby sitting app).Thanks again. I am a believer.

This product cannot withstand Extreme Winter Weather Conditions. I left this antenna mounted on my roof at a seasonal Trailer Park. When I tried to use it this year, it failed, and water was found dripping out of the main USB cable, which was still plugged into the bottom of the antenna. This shows that that antenna case is not weatherproof, and needs to be sealed or protected within a plastic pipe, concealing both antenna USB cable connector from the weather. However when it works, it does pull in WIFI signals as advertised.

This device is awesome. As a contractor, I can not access my customer's network for security reasons. I had to tether my laptop to my phone to get an internet connection. Now, with my office on the second floor, I can connect to a WiFi hotspot 1.5 miles away and my signal strength is strong!

I received the Super USB WiFi Antenna 3 today. I quickly hooked it up and stuck it to the inside of one of my RV windows just to see how it worked. I was immediately absolutely amazed at the signal strength and quality of my Wifi signal. Where I was getting 2 bars, now I'm maxing out the meter. I am also picking up 11 other strong WiFi signals and I haven't even put the antenna outside yet. And another point, my signal is now consistent, where as before it was in and out. I highly recommend this Antenna to anyone who needs to boost their signal strength.

The unit was shipped within a couple of days and installed flawlessly with Mac 10.7. It has performed as advertised and appears to be well made. It is easy for the connector at the base to become loose, so this needs to be checked regularly (weight of the cable hangs on a mini USB plug). Overall, I am glad that I bought it and recommend it to others who need to extend their WiFi range.Caveats - I doubt that anywhere near one mile is obtainable in the real world. My experience is that about 500' under real world conditions (both ends beside a window, ground level, some foliage between) is the max. In my case, from inside wooden buildings with several walls in the way, the unit works well to about 200'. Beyond that the router will disconnect regularly as signal strength varies. That is enough range to justify buying it for connecting one building to another.If you are beyond normal WiFi range, but well within shouting distance, this is probably going to work for you.Ian Baines, Burlington, ON

While plugging this unit into the usb port on the bottom of the antenna, the port receiver snapped of the contacts and disappeared up into the antenna. I am hoping it was just a fluke that this happened, so I have reordered the antenna and I am going to return the one I have for what I hope will be a pleasant return experience with C. Crane which I am sure it will be.

The Super USB Antenna 3 blows away all of the WiFi antennas that I have previously used. As a "professional tourist", I am always looking for WiFi hotspots to connect to, to surf the web, and to stay in touch with friends and family while on the road. I probably shouldn't write this, but it is also a great back-up if your home internet service should go down too ;). Highly recommend this antenna!

I'm sorry but I am VERY disappointed with the product. I installed the software as instructed, no problems. However the end result was TERRIBLE. It didn't pull-in ANY signals any better than a much cheaper antenna I'd purchased in the past elsewhere. I was expecting a lot more. I gave it away to a friend. I was so disappointed. Sorry....just stating the facts.Big expenditure and big disappointment.

This product is used to access University of Hawaii's wireless network from a workshop inside a concrete building. Most built-in notebook WiFi adapters at this location get 1/5 bars of signal at most, while the Super USB WiFi gets 3/5 bars consistently.

All I can say is WOW. I've been struggling with a weak WiFi signal in our home for the past four years. I've tried router antenna extensions, relocating the router, three different routers and I still couldn't get a decent signal to my wife's computer. It was to the point of being very aggravating (her complaining about it). I installed this antenna on her computer in about five minutes and now she has full signal strength and I can see other router signals from at least a four block radius. In summary - excellent product, performs as specified and best of all - marriage saved. Thank you.

There are a couple of really neat features about this product. One nice feature is the very high gain ... while I intend to use it in my RV, I got excited when the antenna arrived and I stuck the antenna on a window close to my computer and I picked up signals that were not in range with my WiFire (formerly, my favorite choice when traveling). The next nice feature is that the antenna is omni-directional ... no longer will I have to carefully scan an area with a highly directional antenna. The next nice feature is the long cable and the fact that it can be used outdoors. The final nice feature is that the optional software is excellent, assuming that you want to fuss with the antenna.

  • Which side (front or back) faces the window when using the suction cups?

    It's up to you. The Super USB Wi-Fi Antenna is Omni-directional, and so it can receive the signal from any direction.
  • Can I use a passive USB extension cable to add on to the existing length of the cable that came with the Super USB WiFi Antenna?

    No, the Super USB WiFi Antenna should not be connected to an additional passive USB extension cable. Please use the 15ft USB cable that came with the antenna or replace it by purchasing an optional 30ft USB cable. It is not recommended to exceed the 30ft USB cable, as it can cause severe signal loss.
  • My computer is not showing that the antenna is plugged in. What is wrong?

    Check the connection between the antenna and the cable to be sure they are tightly connected. If only one USB port is available, make sure to use the main USB cable connector, not the optional Power Boost connector (single loose connector).
  • My software shows that the antenna is connected but when I try to use my internet browser I am unable to view anything. What should I do?

    You may not have a strong enough WiFi connection. Successful connection to a wireless network usually requires a minimum of 2 bars of signal. If the signal is low, you can try relocating or repositioning the antenna with a better line-of-sight view to the WiFi source; or the wireless network does not offer internet service; or a firewall/virus protection is preventing access.
  • I purchased the USB WiFi Antenna and when it is hooked up it does not improve my WiFi reception. Is there something I can do to make it work better?

    Be sure that the antenna is positioned vertically in the center of the window, if the WiFi source is outside your location. Using the optional 30ft accessory cable, you can mount your antenna outside and up high for best reception. Please consult the Assembly Guide (or Tips section of the Quick Start Guide) for weather proofing instructions.
  • My computer has an internal WiFi antenna; is it necessary to disable it before installing the software and the Super USB WiFi Antenna?

    It is not required, but it is recommended. If both WiFi connections are going at the same time, it will require more power from your computer and create extra heat. Usually there is a button, switch, or key on a laptop that disables the built-in WiFi device.
  • Do I need to use the Ralink WLAN Utility supplied with this antenna?

    Installing the “Driver Only” is the easiest way to use your antenna. We recommend that only advanced users and Windows 2000 users install the Ralink WLAN Utility. For more assistance using the Ralink WLAN Utility, refer to the full user manual on the supplied CD.
  • What does IP65 stand for?

    IP followed by two numbers are protection ratings that are applied to indicate how well an enclosures protects against water, dust, oil, or other ingress. These ratings were established by the International Electro Technical Commission. IP itself stands for Ingress Protection. The first number being a 6 means: Totally protected against dust ingress. The second number being a 5 means: Protected against low pressure water jets from any direction. Limited ingress permitted. In layman’s terms it means the product is dust proof and water resistant.
  • Why are there two USB input connectors on this antenna cable? If I can only use one on my computer which one do I use?

    One USB connector is for power and data transfer, the other is for a boost to power. You will want to use the power and data USB connector which is the one with two cables attached to it.
  • I am using MAC OS and installed the software and hooked up my Super WiFi Antenna-3. It shows successfully connected but I have no IP address and no internet access, why?

    It is possible to be using the wrong encryption key and for the software to still say you are connected (because all the steps were followed). Please check your encryption key again to ensure the correct passcode is being used.
  • I am using MAC OS 10.6 and am having trouble installing the software. What can I do to resolve this?

    Please click the Downloads tab on this page and check for the latest driver.
  • I am planning on using the Super USB WiFi Antenna 3 on a boat. Is there anything extra I should consider?

    We recommend that you use Coax Seal to protect the antenna connection from heavy salt water corrosion.
  • I have Windows 7/Vista and inserted the software CD. I clicked on "Run Autorun.exe" but nothing is happening.

    Check the bottom Task Bar area for a security shield or message that is asking permission to install the software. Also, if your computer has a third party Firewall or Virus protection installed, you may have to disable it. Please read the manufacturer’s instruction manual.
  • My computer is a Mac and I connect to a Secure Network but every time I shut my computer down, I have to reenter the Encryption Key.

    Connect to the network and click on “Add Profile”. See “Creating a Profile” on page 12 of the Quick Start Guide for more information.
  • I use the antenna with my iPad? or iPhone? to increase my WiFi reception?

    No. The Super USB WiFi Antenna 3 requires installation of software drivers. The iPad® and iPhone® are not capable of installing software drivers.
  • What do the blue and red lights on the antenna mean?

    The flashing blue light means the antenna is getting power and the intermittent red light means the antenna is communicating with the computer.
  • Will the Super USB WiFi Antenna 3 work with Windows 8?

    Yes it will. In most cases all you have to do is plug in the antenna to your computer using the supplied cable and Windows® 8 will install the device. In some rare cases you will need to be near a hot spot for Windows® 8 to locate the drivers. The drivers on the CD will work but the software will not auto-run when the CD is inserted (you may have to manually start the CD). The drivers are on the page for the antenna under the “downloads” tab for future reference should you need them.
  • This antenna claims to boost WiFi up to 1 mile. How was this tested?

    We tested the range from the top of a high beach bluff to a road below that had no obstructions. On the top of the bluff, we pointed a 12dBi directional panel antenna to the road below. We stopped at 1/4 mile intervals and tested the WiFi connection and internet usability. At 1 mile a connection was made without a problem. We continued down the road testing for more range. At 1.25 miles the connection remained but was slower. At 1.5 miles, the antenna was out of range. It is theoretically possible to increase the distance by upgrading the access point's 12dBi WiFi antenna to a larger antenna.
  • USB WiFi Antenna 3 Connections, Old vs. New

    If you purchased your US3 before March 25, 2013, then your antenna has the original connector shown in the picture on the left. The connector plugged into the base of the antenna. The current model of US3 now has the connector hardwired to the antenna, which cannot be removed (see picture to the right). The USB connection on the current version is now further down the cord, improving flexibility and weatherproofing of the connection. We changed the design due to suggestions from customers who own the older version of the antenna and worked to prevent any connection failures.
