Just a simple reminder that you get what you pay for. I purchased a dual band high gain antenna, called a Bingfu High Gain Antenna, and surely wasted my money in doing so. It's a fold over antenna that folds over when you're driving down the highway. I tried it on my Kenworth T680 and on my Mazda 3 car. It doesn't discriminate on type of vehicle, for sure! So, pay more and worry less, rather than pay less and worry more.
