Wilson Booster

I have the other antenna posted. It came with a 3watt system I bought before the Sleek series was sold. It didn't improve my Sleek system signal level. It might work better with different vehicles and different terrain. I've talked a couple of friends into the Sleek. There are many little factors that affect actual signal level. The older Iphone 3G doesn't seem to like the booster. All newer Iphones have no problem. Motorola's seem to respond faster and slightly better with the Sleek.
