If you ask us personally, then the ultimate choice, that we would recommend you is TP-Link 2. For the rest options, read the article till the very end. Here is our comparative guide to the outdoor wireless bridge available as well as our recommendations.
TP-Link 2. Power Consumption: Supports the latest Both 2. AP mode Set up as an outdoor wireless access point is recommended for bigger yard. Lightning Protection, Waterproof, Dustproof, Antifreeze, High-Temperature Resistant, Antioxidant, ensures stable connection in harsh outdoor conditions. It supports pole or wall mounted. Comply with IEEE Discreet appearance can also fit with any indoor scenarios. So, if you would like to know the detailed insights then make sure that you read the article carefully till the end.
We always take that extra step while reviewing products, so that our user base only gets exposed to the best and reliable omni directional wifi antenna. But, if you are still looking for something more cheaper and reliable, then you are free to go for Vandal Resistant Low Profile Dual Band 2. The table below provides a quick overview of the Top omni directional wifi antenna. You can take a look on the design before reading a complete review.
Plus, the features that make each product stand out from the crowd are highlighted, with a view to save your precious time. More Info and Images 10dBi 2. Our quality built omni-directional antenna is a direct replacement for the antenna that comes standard with your router, access point, VOIP device, or PCI card. Because it is omni-directional, no aiming is equired - it can send and receive WiFi in all directions. More Info and Images Highfine 2 x 2. Does not improve signal for cell phones or other devices not directly wired to the antenna.

To really find out you need to dig into the datasheet of the antennas. It is worth noting that antenna manufactures will always do their best to try to make their antenna sound better than the competitors.
This means they might measure their antenna gains in slightly different ways in order to get the biggest number possible. With any good antennas, you will be able to obtain proper antenna patterns.
The existing answers have mostly addressed your question, but just for posterity, I want to clarify a couple things. You have to be careful with dBi, as it is not equivalent to total radiated power. Different antennas can have drastically different efficiencies.
What dBi tells you is the peak gain out of all possible directions when compared to a perfect antenna that radiates uniformly and omnidirectionally isotropic.
You should also note that this is a ratio, and that it is on the logarithmic scale, so 3 dB is 2 times more, whereas 20 dB is times more and the i in dBi means isotropic. Anyway, the important thing to realize is that a 2. When you are in line-of-sight LOS environments this peak gain is probably all that matters, as long as the antenna is in fact correctly pointed at the other antenna. In these NLOS environments the efficiency of the antenna total radiated power often matters a lot more than the directivity dBi.
This is never achievable in reality, as it is always a gradual change in gain notably, when you look at beam patterns they typically draw the 3 dB line, a heatmap would show a gradual change. Though, in reality, even with ground bounces you can get some screwy interference patterns. Final thought -- if you look at a free space path loss calculator, e. Your 7 dBi antenna would give another 75 m, up to m for the same pathloss. You should also note that you can be breaking the law with too high a gain of antenna -- the FCC limits unlicensed transmission in the 2.
Also, at some distance the bluetooth protocol will probably actually start to fail, as the latency from speed of light about 1 us roundtrip at m can break things though I'm much more familiar with WiFi. Yes Isotropic means true "omni-directional. Since a rubber ducky, or patch antenna has null zones it sends more in some directions broadside to the antenna. Gain and beamwidth of peak direction are tradeoffs from isotropic. What this means to you is that when you are on the fringe, they can now aim to get 5dB more which is huge and that gets you into error free mode.
But like a narrow beam headlight, it also means if are far away and do not know the direction to the router or cell tower, you are more likely to get lost until you monitor your RSSI or received signal strength indicator on the cell phone. For Wifi however, it serves a dual purpose. Once a connection is made it reverts to baud rate and not signal strength in some cases such as Apple's OSX, and if you lose the signal , then you have to aim to maintain a good connection.
For direct ideal "interference-free" point to point in clear line of site, 5 dB improvement means you can nearly double your distance.
This rarely happens in the city, so distance is not as significant as ability to aim towards signal and away from interference. If one wanted to calculate path loss they might use the "Friis Transmission Equation" for path loss. This does not account for receiver noise floor, multi-path dead zones and path loss from buildings, trees, rain etc. Range, R is in meters, as is Lambda the wavelength of transmitter Ft and gains for both antenna Gr, Gt. I'm not an expert on antennas, but I've heard about directive antennas.
The "i" in dBi stands for "isotropic", meaning uniformly radiating in all directions.
