ATNJ AS-P1 PCS 1900 Cell Phone Signal Booster 3G UMTS 4G LTE 1900 B2 Celluar Mobile Phone Repeater Smart Amplifier for Home Boost Calling Talk Voice and Internet

I put the antennae on the roof overhang, and the amp in my window. Went from getting -70db signal to +05db signal.Still only getting one bar. Very hard to get proper placements, but i guess it works. Barely, I'd say. I would be interested to try a different product and compare the results.

POS DOES NOT WORK. One moment says weak signal next says isolation. When it works it does not boost any signal. TOTAL WASTE OF MONEY

Did not improve reception at all
