Bingfu Dual Band WiFi 2.4GHz 5GHz 5.8GHz 9dBi Magnetic Base SMA Male Antenna for Wireless Vedio Security Camera Surveillance Recorder Vehicle Truck Trailer Rear View Backup Camera Reversing Monitor

I was looking to extend the range of my wireless security cameras and decided to give these a shot. After extensive testing, I learned that these antennas don’t really extend the range of the stock antennas that are on my cameras, HOWEVER, I discovered a trick that GREATLY extends the range. My front gate is roughly 200 yards from my home (and NVR). Using just the antenna, about 65 yards is the limit, and the signal is weak. The camera is always “behind” in time, and nothing is recorded about half the time. I decided to use an old satellite dish to direct the signal towards my home, and I’m amazed at how well this works. Full signal strength from my front gate! Now I’m curious as to how far I can make this set-up work. Thanks GoogleFU errr… BingFU!

Kicks ass with NightHawk! Went to cellular wireless for TV and internet at the house. Wanted to see if we could get a little more out of the modem so we bought these and another little plug in antenna. Tried multiple locations and configurations with both antennas, different locations in the house, different distances between antenna ect ect. Found that setting the Nighthawk on its side so the internal units are “broadside” to the tower and one BingFu unit about 4′ away on the window sill with a command strip to keep it upright works great. Streaming about 100 gig a month. Streaming D+ and still using wifi for ipads and no real issues. This little unit probably gave us a 100% boost in signal. Worth every penny. Just make sure you get the right connector for your unit and then try different places in the house and different layouts for the antenna.

Did not work for my application. I’m not a radio frequency nerd, but all specs seemed to match up what I needed for my wireless backup camera system for my RV. Antenna actually performed worse than the stock 3 inch antennas. Antenna, wire, and fitting quality is fine. Magnetic base is trash. They used a super small magnet that is lightly glued behind a hollow plastic base. Came apart during first application. Epoxy and a large magent would be required as a diy if that is how you plan to mount. Stock, this antenna cant hold itself to a metal object, even upright. It’s that weak. I wound up using 3m double sided, electric tape wrap, with a tertiary zip tie.

Package came to my house as described.Contents were all there.Antenna was a lot smaller than I thought it would be but has boosted signal somewhat.Magnet is not very strong but it works fair!Glued a stronger magnet to the antenna magnet now works great!

Bought these as spares for field test last December, so this is specific to shipments during that period – package had bar code X0028EFDJF. Just used them for a new field test – at 2.4 Ghz they are terrible – collected signal strength data – they are closer to -5 to -7 db gain – certainly not +9 db. Junk, at least at 2.4 Ghz.

These high gain antennas are supposed to have radiation patterns where most of the RF energy is directed perpendicular to the antenna – so when vertical, they radiate out parallel to the ground. For 9 db of gain, typically the strong signal is from fifteen degrees below level, to 15 degrees above level. a 0 db antenna radiates in all directions (omni-directional.) So these should be great for terrestrial deployments – lousy for airplanes (or drones). But I am using them terrestrially – probably within 2 to 3 degrees of horizontal. A 6 db increase will double the range. I just tested these against a 2 db gain antenna using the same radios at 2.4 GHz. The cheap 2db antenna has a range almost three times greater than these antennas.

We have also tested an L-Com RE05U that is listed as a 5db antenna – it has worked at a range four times the range of these Bingfu units, with rock-solid, reliable communications at three times the range of these units.

The RE05U is specifically designed for 2.4 Ghz. Unfortunately not sold at amazon.

Two possibilities – the six units I bought in early December were defective, or these antennas were not designed to work at 2.4 Ghz. Note that a lot of modern wi-fi uses both bands (2.4 and 5.8), so it may be they work at 5.8 and people don’t realize they do not work at 2.4. But if you are using IEEE802.15.4 (as we are), 5.8 is not an option.

No more twisting and tilting my router to receive the signals from my Foscam cameras on the other side of my garage doors, just thread the cables through and hang halfway to my den and I get GREAT signals!

Item arrived safe and sound. Worked well on my 44′ rv. Just need a little more reach on the backup camera and this accomplished that.

Worked great as an add in to my WiFi backup cam on RV. Stock antenna sucked and wouldn’t reach to the cab of my truck. Now with this antenna I can be much further away than I need to be. No problem. Quick shipping. recommended
