Pros This unit works very well in the hills and valleys of Central NY. It gets me coverage in areas that were not available before I started using it. I placed the unit behind the passenger seat in my car.
Cons The connecting line is too short.
Summary Considering the cost and simplicity of the connection it is worth trying first before spending the big money.
Pros Nicely priced, long cord, small size
Cons Nothing really. I got more then I paid for out of this.
Summary I live in Murfreesboro, TN and I use Sprint as my high-speed wireless carrier. I use the Aircard 595U. In some areas around here the service is weak. This area has grown so fast that Sprint is just starting to build new towers. In Nashville the coverage is solid. Even down the road from my house is solid. It is just in my area where the service comes and goes.
To be honest, I did not think this thing would work because the box looks kind of gimmicky. It's bright orange and has a guy sitting at a desk with the antenna. So for at least me, it seemed like it might not work. But for $30 it was worth a try.
The antenna really did help me out. My card at home would register 2 to 3 bars. The moment I plugged the antenna in, I got 5 bars. The speeds went up by 100 to 200Kbps. So overall I am very happy. I really like the fact that the antenna is small when compared to some antenna's. It is around a few inches smaller then a DVD box. It looks a lot like a vehicles horn box.
I also use the Sprint wireless router, so this antenna is small enough to carry around. In the more solid coverage areas of Nashville, I will max out the bars. The speeds go up to around 1 to 2.5Mbps on average. Which is very useful when I am sharing the connection through the router.
So if you have weak service, or just want better, it is worth a shot. If you don't like it, then send it back. But since I have ONLY used this antenna with Sprint, I do not know how it will fend with other carriers.
Also, if you have Verizon or Cingular, you do not really have unlimited. They have a cap of 7GB's of data a month. So they have all kinds of complaints from customers over having their accounts canceled for going over that. I am just letting you know this because if this antenna does boost your speeds, don't go crazy with the downloads, streams, or VoIP if you have 1 of those carriers. They will cancel your account.
