I bought this antenna primary for indoor use - I have a Verizon MiFi which I use in the car on trips and at work. It works wonderfully in the car - I did a speed test before and after hooking the MiFi to it, and the speed I was able to get improved from about 100 Kb/s to 500 Kb/s, and it remained stable as I drove on the PA Turnpike - was even able to stream Netflix - though I just did that as proof of concept, don't want to burn my bandwidth that fast :).I was able to get it to work indoors by putting it on a cookie tin, though the speed improvements weren't as noticeable - I will be using it at work starting Tuesday - will update once I see how well it performs there.
