Review: Worked great boosting Bluetooth signal - I use this antenna and cable to boost the Bluetooth range on a Denon DZ-300 media player in a school gymnasium. It increase the range from 50 feet to over 150 feet. The rack where the unit is located is on stage in the very back corner which is part of the gym. The stage itself is 30 feet deep and the gym would add another 120 feet. So the range is at least 150 feet. I don't know the maximum range because I do not have access to the building adjacent to the gymnasium. I can now go anywhere in the gymnasium or on stage with no dropout issues.. I'm very happy with the purchase and would recommend it if you were having Bluetooth range issues. One thing to make sure you check before purchasing is the polarity you need for your antenna. this antenna and cable are reversed polarity (RP) so make sure you check with your device manufacturer. The easiest way to check the polarity is on your device where the antenna screws in if there is a center pin sticking out on the unit where the antenna screws in it is reversed polarity. If there is no center pin sticking out where the antenna screws in to the unit it is standard polarity. I hope this helps you.
Review: Great product! It finally resolved the low-signal issue on one security camera. - I have installed two Xmarto security camera systems that I purchased from desertcart. Both work well overall with the aid of a couple of accessory external antennas. However, I installed the second system at my M-I-L's house which is covered with aluminum siding. I simply could not keep one camera from "dropping out" due to a low signal. I tried a couple of different 7 dba accessory antennas but the camera signal remained weak (1 to 2 bars) and unstable. When I saw that this antenna was rated at 22 dbi I knew that it might do the trick. It did! The camera signal is now three bars and rock-solid. If you are having a weak signal issue I highly recommend this antenna.

### ⭐ No better than OEM antenna
*by J***R on June 15, 2021*

TLDR: This antenna is no better in performance than the stock OEM antenna. I live in a rural area and needed a little more signal to my workshop (a wood building with windows). This item is supposed to be "high gain" for a better wifi signal. After swapping out my OEM antenna on two different Wifi devices (an Alfa 2.4 ghz, and a pepwave 2.4 ghz) neither one demonstrated an improved signal whatsoever. This applied to send and receive traffic. I used a tool to measure signal, so it wasn't just me guessing about the performance. Additionally, by adding the included extension cable to try to improve signal quality via moving the antenna around not only didn't help, but made the signal worse. I saw approximately 20% loss in overall signal every time I put the extension cable into the configuration. Very disappointed.
