Yagi WiFi Antenna 2.4GHz (15dBi) Outdoor Directional Signal (H:30° V:25°) Long Distance Range (High-Gain Weatherproof) Wireless Network (Pole Mount) N-Female Pigtail Connector Tupavco TP512

Hardware: Solid Aluminum Rods for elements, folded dipole driven element with matching network for feed. Some burs on the element ends, no apparent effect on performance. U-bolts with flat and split washers. V-Clamp with U-bolts, Will fit 1 1/4 inch mast (on the small side. Looks like it would easily do 1.5 inch mast. I'm using a closet pole. Jumper cable: 6" Female Type N for feed. Construction: Very solid, nothing wiggles around, elements are well fixed and mounting bracket is firm. All Aluminum construction. RF Performance: Reference setup is: Amped Wireless High Power 1000mW Wi-Fi Signal Booster (SB1000) This antenna is specified at 7 dBi gain and has a companion 1000 mW transmit amplifier in the magnetic base for the vertical 7 dBi antenna. I did the following for the test: Took several reference signal levels 80' away at the location of the wireless adapter for my DirecTV HD-DVR. (30' down a hallway): Reference Level: -56 dBm 1. Pulled power from amplifier. 2. Unscrewed 7 dBi vertical antenna from amplifier base 3. Screwed 6' adapter cable from new WIFI Yagi into the magnetic amplifier base (replacing the vertical 7 dBi antenna) 4. Plugged power back into the amplifier. 5. Aimed the Yagi (vertically polarized), across the room and into the hallway opening. Went to the target location and took a series of readings with the new antenna in place. Since the amplifier was in line for the testing procedure, the only difference in the two setups: 1. 6' of additional feedline to the new antenna (vertical had no feedline, it screwed right into the magnetic base) 2. The new WIFI Yagi antenna Results: Original 7 dBi Vertical Antenna and Amp : -56 dBm WIFI Yagi 15 dBi and Amp: -42 dBm Signal Level Improvement of WIFI Yagi: 14 dB All things being equal, the improvement (in a perfect, non-reflective environment) should have been 8 dB. However, since all the floors are tile and I'm shooting down a long hallway, then into another open room, there are reflections all over the place. I placed my receiving antenna (in the Wireless Adapter) in the position that my signal meter recorded the best signal level. In other words, I "found the hot spot" and put it there. Conclusions: 1. The antenna certainly has gain, and I measured greater gain than the specs due to reflections. 2. The project was very successful in that a small 22" long antenna was able to shoot a High Definition quality signal 80' through our home. 3. Streaming High Definition Video from a DirecTV HD-DVR(Genie) wirelessly worked perfectly, now in both directions. When I was using just the vertical and amp at the transmit end, I could SEND video to the remote location, but I could not PLAY BACK video FROM the remote location. Now I can do it in both directions without any pixellation, stuttering or audio drop outs. I used the recommended 6.5' extension cable (for the WIFI Yagi) to connect the antenna to the amplifier: TRENDnet Low Loss Reverse SMA Female to N-Type Male Weatherproof Connector Cable Overall, I couldn't be more pleased. The construction is first rate, the price was very low, considering the product quality, the RF performance exceeded my expectations and the project was a complete success with two way high definition video being able to be carried from one end of the house to the other over a 2.4 gHz wireless N connection.

I went out on a little limb with this. I had no specific recommendation for this antenna as far as meeting my exact requirement. We have on our property a 30'x 60' enclosed steel building. My wife runs part of her business out of it. It sits about 50-60 feet from the main house. She ordered some security cameras to keep an eye on the building's insides from her office in the house. A First Alert DWS-472 wireless system that claimed nearly 500 feet of reach. Needless to say, that advertised reach did not include a signal-swallowing steel building in the path. Added level of difficulty, the camera was to be mounted in the back of the building. Taking the receiver outside we could pick up the camera's signal about halfway to the building. I knew the signal just needed a little nudge to make it to the house, nothing fancy, but it would need to be external. Researching the camera I discovered that it used the same frequency, 2.4GHz as Wifi, and the same connectors. I could find nothing from First Alert itself about attaching an external antenna, except that you could. They offered none themselves. I found many external antennas for WiFi and based on price and reviews went with this one. I found a cable listed on Amazon as well that sounded like it had the right connectors. (WiFi Antenna Cable 20ft - RP-SMA Female to N Male Pigtail Connector Adapter Jack) So I went for it, fully expecting a follow-up order or trip to an electronics retailer to get the right connector, adapter, etc. The antenna and the cable arrived in separate packages, three days after my order was placed. I only spent a couple of hours on Saturday testing and finally installing it. Alignment was eyeball only, no calculus or trigonometry required. I just leveled the (not included) standard antenna mast brackets and mast (also not included, but inexpensively available at home improvement stores) and pointed the antenna in the general direction of the middle of the house. Flawless. We now have full signal strength everywhere in the house from the back of the steel building. Simple, sturdy, light weight, everything we required. And yeah, the cable had the right connectors as well. Very pleased with the quality and signal strength improvement. I’m not sure about the math and technical specs, but this antenna simply worked without requiring an engineering degree in RF wave propagation. Recommended!

QUICK REVIEW: If you intend to use this antenna in a relatively "quiet" radio environment (maybe on a farm, across a large swath of land, or in a "wifi-quiet" rural area), then I'd say it will probably work nicely for you. It's a good price for a reasonable boost to reception in this kind of environment. If you intend to use this antenna in an environment with lots of other wifi signals competing for reception, I'd say this antenna won't help at all. It would be just as likely to pick up signals from one of its sides or from the back, which would interfere with the signal you are intending to receive. In this case, you'll need to go for a more expensive, higher (true) gain Yagi. (FYI there's a really inexpensive, 24 dBi parabolic dish available here, as well. It is very good for the price! I believe it was around $ 45.) TECHNICAL REVIEW: My field-testing of this device suggest it isn't really a "15 dBi gain" antenna. As far as I can tell, this antenna only gives you, maybe 8 dB absolute gain from the front, which equates to around 11 dBi. It may not sound like much of a difference, but there is a lot of antenna engineering between the 15dBi claim and an 11dBi, actual. Additionally, this antenna has asymmetrical front-to-side characteristics. Front-to-one side is -18db (which is awesome!). Front to the other side may only be about 9 db (which is... meeh.) Just to be complete, the front-to-back is maybe 6db (which can be bad, depending upon your needs). So, while I'd say that this antenna is, indeed, a gain antenna, it is not as high as what is being claimed, and its asymmetrical receive pattern may prove problematic in multiple-signal-source environments.

Excelente antena. Se ve que es resistente y capta muy bien la señal. Cumple con su función

Réception longue portée de signal wifi

aumenta la potencia de recepcion y envio un 30% mas que las normales de mi adaptador alfa

bought 1 to try it and ordered 5 more. this antenna works great to extend and outdoor network and works well in all weather conditions. looks nice quality build and easy to install

Buena antena
