I normaly get about 3 bars of signal. I purchased the wilson trucker antenna, 3 watt amp, 100' ultra low loss cable and the needed adapters and fittings. I used a 6' piece of 1" pvc as a mast to get the antenna as high up as possible. Im now getting the max signal bars but I saw little to no difference in my conection speed. The only upside has been that I have absolutely NO dropped conections. Dunno if it was worth the $500 though. just my expirience
