Très Très efficace

Works great and took less than 5 minutes to install! It greatly increased the range and sound quality of my indoor Bluetooth-equipped amplifier that is wired to a set of hardwired outdoor ceiling speakers. I simply unscrewed and replaced the amp's small 1" OEM antenna with this one, which allowed me to move the antenna into a location more 'line-of-sight' to the backyard. The amp itself remains in an "electronics closet" inside of the house with other electronic "metal boxes", yet now so I can play music outside on my iPhone SE from over100 feet away!

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!

Haven't functionally used it yet but appears to be otherwise as advertised. Tested the magnet and it is definitely not the most spectacular, which is somewhat surprising considering one of the selling points is for vehicles. Wind will be an issue, so I will be replacing it with a neodymium magnet at some point.

a servit a prolonger la portée de caméra sans fil pour mettre en arriere de roulotte.
