I use it with a good 20 db gain permanent roof antenna and a digital 3 watt signal booster, improving my range by 10's of miles and eliminating the largess of dropped calls when I'm out working/ driving in the boonies of Wyoming and other places in the Rocky Mountain boonies

Wilson antenna works with it as well and fits the same cable connection

Works fine, allowing external antenna for most cellphones, greatly improving signal strength in the boonies

Disappointing as the last time I spoke with Tech Support the person I spoke with was very knowledgeable and helpful.
