I like the antenna and get good strength, even better than with the receiver on the dash, I just hate the MMCX or whatever that connection is on the Holux. Any movement will disconnect the cable and it's really fragile like it could break anytime. The antenna doesn't seem to help my cell reception when connected and I don't use the wifi (I use EVDO) but I like the clean look and can hide the GPS receiver. I already had a hole in my roof from a factory sirius setup which I used.
