This is very easy to install ( Unscrew the old screw on the new one) The High Gain SMA 3G/4G/LTE Antenna improved the signal strength on my old IPDATEL Alarm Communicator (I believe mine is CAT/CDMA Dual) from 2 bars (signal strength lit) to 3 divisions ( signal strength indicator) in just a few seconds. Given that 2 is the minimum recommended signal level for me, 3 is 50% better than 2 and I'm happy with that.
