The Wilson/Weboost cradle booster is amazing. It will turn a one-bar signal into 4 bars easy even with my omni antenna. I want to try the directional to see how much better signal I get.
The directional antenna allows me to get further out. I have a truckers antenna permanently mounted and when that is not enough, out comes the directional one.
I got my setup about four years ago. Back then the cable they offered was about twice as thick and I needed to get three different adapters. This looks like a better solution.
